ICSE Class 10 · Computer Applications (Java) · Specimen paper and mock tests 2027

ICSE Computer Applications specimen paper and mock tests, solved live.

The CISCE specimen paper tells you what the 2027 Computer Applications paper will look like. It does not tell your child why their output-prediction answer was wrong, why a working Section B program still lost four marks, or how to fit four programs and forty short answers into two hours. In our live mini batch the specimen paper is solved together in BlueJ, then full two-hour mock papers are written, marked like the board, section by section, and reviewed with doubts answered live.

Ans. The short version

The best way to use the ICSE Class 10 Computer Applications specimen paper for 2027 is to solve it twice: once untimed, to learn the question shapes of Section A and the program families of Section B, then as a full two-hour mock. The theory paper is 100 marks, Section A forty compulsory short-answer marks and Section B sixty marks of Java programs written with variable descriptions, plus a separate 100-mark internal assessment. Modern Age Coders solves the CISCE specimen paper live in BlueJ, then runs three full two-hour mocks marked section by section, monthly BlueJ practical mocks, an internal assessment rehearsal and live doubt solving, in a Tuesday 5:30 PM and Wednesday 8 PM IST mini batch or personalised one to one.

Q1. What is in the CISCE specimen paper?

The specimen paper is the board telling you the paper's design in advance

CISCE publishes specimen question papers for ICSE subjects ahead of each examination. For Computer Applications, the specimen is the single most useful document a Class 10 student can hold.

What it fixes for the year

As of 13 October 2026, CISCE's specimen paper index runs up to the 2026 examination, and the latest official Computer Applications specimen is the one issued for 2025. The syllabus for 2027 is unchanged from 2026, so that paper is still an accurate guide until a newer one is published, and we solve whichever specimen is current. The specimen sets out the paper's design: the instructions on the cover, how Section A's forty compulsory marks are divided into objective and short-answer questions, how many Section B programs are offered and how many must be answered, and what the paper expects every program to carry. In the current specimen, Section A is Question 1, twenty multiple-choice questions of one mark each, and Question 2, ten short questions of two marks each, all compulsory, for 40 marks. Section B is Questions 3 to 8, six programs of 15 marks each, of which any four are answered, for 60 marks. Programs may be written in BlueJ or any Java environment.

What it does not include is a mark-by-mark explanation of the answers. That gap is where students lose marks without knowing why, and it is the gap a live solving class closes.

The instructions students skip

Section B programs are expected in Java, with variable descriptions or mnemonic codes so that the logic of the program is clearly depicted; flowcharts and algorithms are not required. Students who write a correct program and leave out the variable description are giving away marks the paper told them how to keep.

Section A rewards precision rather than length: exact Java terms, outputs traced character by character, one statement of Java written exactly. The specimen's objective questions show how fine the distinctions are, and why guessing from the shape of the code fails.

The 2027 written paper: CISCE had not released the ICSE 2027 timetable when we last checked on 13 October 2026; last year's appeared in mid-November. The 2026 ICSE examinations ran from 17 February to 30 March, so expect Computer Applications to fall inside the February to March 2027 window. For the full CISCE timetable, the internal assessment window and every rule of the paper, read ICSE Computer Applications exam date 2027 and pattern.

Q2. How does the mock test series run?

The ICSE practice ladder: a diagnostic first, an examiner rehearsal last

Every paper below is written, marked and returned in a live review where lost marks are re-attempted on the spot. A Java mock reviewed only by its score teaches almost nothing.

PracticeTimingHow it is setWhat your child walks away with
Starting diagnosticWithin two weeks of joiningShort Section A set plus one Section B program, timedA map of which units leak marks, usually Section A before Section B
Section A shape drillsEvery TuesdayOutput prediction, loop counts, differences, one-line JavaForty compulsory marks practised by question shape, not by chapter
Program family setsEvery WednesdayOne program per family in BlueJ, with variable descriptionArrays, strings, menus, overloading and number programs kept warm
CISCE specimen paper, solved liveOnce the specimen for the year is out, from DecemberUntimed first, then a timed re-attempt of each sectionThe year's design learned straight from CISCE
Full mock 1Early JanuaryFull 100-mark paper under two-hour conditionsReviewed in two halves, Section A on Tuesday, Section B on Wednesday
Second and third full papersFrom late January until the examFresh papers in the specimen's designA rising score and a time plan that no longer needs thinking about
Internal assessment rehearsalBefore the school's practical windowLab file review, examiner questions, one unseen program in BlueJThe 100 internal marks rehearsed with an unfamiliar examiner

The order is deliberate. The lab file of twenty or more assignments is closed before the school's internal assessment, so January belongs to the written paper and its three mocks. Mock papers follow the specimen's design but use fresh questions, so a student who remembers last week's answers gains nothing; only one who can trace and write Java does. The time plan for the two hours and the full countdown are set out in our ICSE board exam preparation guide.

Q3. What happens in a live paper-solving class?

Up to six students, one shared BlueJ screen, every answer marked aloud

The mini batch exists for exactly this: in a class of up to six, every student's answer can be read, run and marked in front of the others in a single session.

  1. Name the question's shape before answering

    Output prediction, loop count, difference, error correction, one statement of Java: Section A has a small number of shapes and each has a method. Naming the shape first means the method arrives before the guess does.

  2. Answer against the clock

    Section A is roughly a mark a minute in a two-hour paper with sixty marks still to come, so the clock is part of every Tuesday drill, never a surprise saved for January. Each Section B program gets its own fixed allowance too.

  3. Trace on paper, then run in BlueJ

    Each student's output is compared with the real output from BlueJ on the shared screen. The trace table that got it right and the shortcut that got it wrong are both shown, which teaches more than a correct answer alone.

  4. Mark the program the way an examiner would

    For Section B, the class marks a program part by part: the class and method structure, input, the logic, output in the format the question asked, and the variable description. A program that runs can still lose marks; students see exactly where.

  5. Live doubts before moving on

    Any student can stop the class with a doubt and it is settled on the shared screen there and then. A doubt that surfaced during home practice goes to the top of the next Tuesday or Wednesday session, and with two sessions a week it never sits for long.

Q4. What does a full-marks answer look like?

Two Section A questions, answered by guessing and by tracing

(i) Give the output: int a = 5, b = 2; int c = a++ * 2 + --b; System.out.println(c + " " + a + b); (ii) How many times does for (int i = 10; i > 0; i -= 3) execute?

The guessed answerswhat most students write
(i)  a++ makes a = 6, so
     c = 6 * 2 + 1 = 13
     Output: 13 7

(ii) 10 / 3 = 3, so the loop
     runs 3 times

# Post-increment used too early,
# a and b added instead of joined,
# loop count from division.
# Zero marks for both parts.

Three separate errors, each one common: the post-increment's old value, string concatenation read as addition, and a loop count done in the head instead of on paper.

The traced answerswhat the paper rewards
(i)  a++ uses 5, then a = 6
     --b makes b = 1, then uses 1
     c = 5 * 2 + 1 = 11
     c + " "      is "11 "  (String)
     "11 " + a    is "11 6"
     "11 6" + b   is "11 61"
     Output: 11 61

(ii) i = 10, 7, 4, 1   (body runs)
     i = -2           (test fails)
     Executes 4 times

One line per operation, the type of each intermediate value written down, and a step table for the loop. The method is slower by a minute and right every time.

Nothing here is advanced Java; it is the Class 9 revision unit, which is exactly why it decides grades. Once the left operand of + is a String, every later + joins text, and a post-increment hands over its old value before changing. Tuesday classes drill these shapes on fresh fragments until the trace table is automatic. The full question bank by unit and shape is on the Computer Applications important questions page, and the Section B program families are practised on ICSE Java programs practice.

Q5. How is the internal assessment rehearsed?

A second 100 marks, rehearsed with an examiner your child has not met

The internal assessment is worth as much as the written paper on the mark sheet: at least twenty laboratory assignments across the year, half the marks from the subject teacher and half from an external examiner.

The BlueJ practical mock

From October, every month, students face a program they have never seen, written in BlueJ against a timer: a menu-driven program with a switch, a search or sort on an array, a string program that counts or rebuilds words, an overloaded method set, or a special-number check. The program is run, the output checked against the question, and the student explains the logic aloud.

The marking follows an examiner's eye: does it compile and run, does the output match the format asked, is there a variable description, can the student say why each loop and condition is there. An unexplained program is treated as half a program.

The examiner rehearsal

CISCE's rules let the school nominate as external examiner a teacher who does not teach the subject to that class. So before the school's assessment, a teacher the student has not worked with reviews the lab file and questions the student on it. Typical questions:

  • Why is this variable private, and how does the class reach it?
  • What is the difference between your constructor and this method?
  • Why did you use binary search here, and what must be true of the array?
  • What does charAt return, and what happens past the last index?
  • Which of your programs would you write differently now, and why?

The full plan for the twenty assignments, with CISCE's four marking criteria and ideas that fit the syllabus, is on the project and internal assessment page. BlueJ itself, set up and used properly from the first class, is covered on ICSE BlueJ Java coaching.

Q6. How are doubts handled?

Live doubts with the code on screen

During the class

Classes happen face to face on live video, with BlueJ shared for everyone to see. A student stuck on a program shares it, and the teacher reads it with them line by line, usually asking the student to predict what each line does, which shows exactly where the misunderstanding sits.

From home practice

Programs that would not compile and outputs that did not match are raised at the start of the next Tuesday or Wednesday class and fixed first. In a mini batch of up to six there is time for every student's doubt, every class.

After each mock

The two review classes after a full mock are built from the students' lost marks, so they are doubt sessions by design. On personalised one to one, the whole session follows your child's own doubts and weak program families.

Questions about the specimen paper and mocks

What families ask about the specimen paper and mock tests

Where can I get the ICSE Computer Applications specimen paper for 2027?

CISCE publishes specimen question papers for ICSE subjects on its website, cisce.org, ahead of the examination, and schools pass them on to students. Download the Computer Applications specimen for the 2027 examination and keep it beside your child's practice: nothing else shows as reliably how CISCE intends to set the paper.

Do you solve the specimen paper in class?

Yes. Once the specimen for the year is available, it is solved live: Section A in the Tuesday class and Section B in the Wednesday class, first untimed so each question's method is clear, then re-attempted under time. Every output is traced on paper and then checked by running the code in BlueJ.

How many mock tests do students write?

Three full 100-mark papers under two-hour conditions from January to the board paper, plus a diagnostic paper on joining, weekly Section A shape drills, weekly program family sets, the specimen paper solved live, monthly BlueJ practical mocks and an internal assessment rehearsal. Each paper is reviewed with lost marks re-attempted.

Are the mock papers previous year papers?

No. Previous papers and the specimen are used for practice in class, but the three full mocks are fresh papers in the current specimen's design, so a student cannot pass them on memory. The board paper will be new too, and the mocks are built to prepare for that.

Does the mock series cover the internal assessment?

Yes. Monthly BlueJ practical mocks start in October, and before the school's internal assessment window each student's lab file is reviewed and the student is questioned on it by a teacher they have not worked with, the way an external examiner does.

Why do students lose marks on programs that work?

Usually for three reasons: a missing variable description, output that does not match the format the question asked for, or a program that answers a slightly different question from the one set. Our mocks mark each part separately so students see exactly which part cost them.

Is ICSE Computer Applications the same as ICSE Computer Science?

In Class 10 the CISCE subject is called Computer Applications, and it is taught in Java with BlueJ. Many families call it ICSE computer science or ICSE Java; it is the same subject and the same paper. Computer Science is the ISC subject in Classes 11 and 12.

Can a student abroad join the same mock series?

Yes, one to one. CISCE lists ICSE schools outside India in the UAE, Singapore, Indonesia and Thailand, and they follow the same Computer Applications syllabus and paper design as a school in Kolkata. Outside India we teach the specimen paper, the full mocks and their reviews personalised one to one, at a time set in your own time zone, usually straight after school.

How much does the mock series cost?

There is no extra charge for the papers. Mocks, specimen solving and reviews are part of ordinary teaching, so you pay only the monthly fee for the mini batch or for personalised one to one, shown above in your own currency. There is no admission fee and the first session is a free demo.

Is it too late to join for the 2027 paper?

Rarely. Full papers begin in January, and a student joining by about November can still finish the twenty-plus lab assignments with catch-up help. A December or January joiner is better off one to one, where the lab file and the three papers can be packed into a private timetable. The free demo gives you a straight answer for your child.

Start

The free demo is a real Section A and B session

Ask for a demo and your child joins a live session working through part of a Computer Applications paper: a few Section A questions traced against a timer and checked in BlueJ, then one Section B program written and marked part by part. You see the teacher, the marking and the live doubt solving first, and the mentor then gives an honest view of whether the mini batch or personalised one to one suits the months before the paper.
