Program Overview

AP Computer Science A is a real first course in programming, taught in Java, and this course treats it that way: you leave able to write Java, not just to pass a test. It is also built for the exam as it exists now, not as it existed last year. The College Board redesigned AP CS A for 2025-26, collapsing the old ten units into four, moving the whole exam onto the digital Bluebook platform, and changing what is tested. Inheritance, polymorphism, interfaces and writing recursive methods were removed. Reading text files with Scanner, working with data sets, and tracing recursive calls were added. A course still teaching the ten-unit format with an inheritance unit is preparing students for an exam that no longer exists.

The six-month structure follows the four redesigned units in order. Months 1 and 2 build Java from nothing and cover Unit 1, using objects and methods. Months 3 and 4 cover selection and iteration, then class creation, which is exactly what the class-design free-response question asks for. Months 5 and 6 cover data collections, arrays, ArrayList, 2D arrays, file reading and data sets, then turn fully to exam craft: all four free-response question types drilled against the real rubric, multiple-choice strategy for the forty-two-question digital section, and full timed mock exams under Bluebook-style conditions. Every class is live and small, and every concept is practised by writing code, because that is the only way this subject is ever actually learned.

What Makes This Program Different

  • ✓ Taught to the 2025-26 redesign: four units, the fully digital Bluebook exam, and the current content, so no time is wasted on inheritance, polymorphism or writing recursion, all of which were removed
  • ✓ The added topics are covered properly: reading text files with Scanner, working with data sets, and tracing recursive calls, which many older courses and books still omit
  • ✓ A real Java course, not a cram sheet: students finish able to read and write Java, which is the point of a first programming course
  • ✓ Free-response mastery against the actual rubric: all four question types, drilled until earning points is a habit, with partial credit understood
  • ✓ Digital-exam readiness: multiple-choice pacing for the forty-two-question section and full mock exams run under Bluebook-style conditions, so test day holds no surprises
  • ✓ Live, small batches where you write code during class and get it reviewed, not lecture videos you watch alone

Your Learning Journey

Phase 1
Java from scratch and Unit 1: primitive types, expressions, Strings, the Math class, and using objects and methods correctly
Phase 2
Units 2 and 3: boolean logic, conditionals and loops, then writing your own classes with constructors, methods and encapsulation
Phase 3
Unit 4 and exam mastery: arrays, ArrayList, 2D arrays, files and data sets, then all four free-response types and full timed digital mock exams

Career Progression

3
A genuine first step toward a computer science degree or any programming-heavy field
4
Free-response and problem-solving habits that transfer to college coursework and technical interviews later
5
An honest, evidence-based read on a realistic target score for your level and the work to reach it
