  • Arrays & ArrayLists: Master creating, initializing, accessing, modifying, and iterating through arrays and ArrayList objects. Understand common pitfalls like ArrayIndexOutOfBoundsException and NullPointerException.
  • Sorting & Searching: Understand the logic and implementation of basic sorting algorithms (e.g., selection, insertion, bubble, merge, quick) and search algorithms (e.g., linear, binary). Know their time complexities.
  • Practice FRQs: Tackle FRQs involving OOP design (e.g., creating subclasses, implementing interfaces) and algorithm implementation (e.g., recursive methods, sorting).

Step 5: Weeks 5–6: Data Structures, Exceptions & Debugging

• Focus: Explore more complex data structures (2D arrays, linked lists, stacks, queues), handle exceptions gracefully, and hone debugging skills.
• Actions:
  • Data Structures: Understand the structure and usage of 2D arrays, linked lists (node-based), stacks (LIFO), and queues (FIFO). Practice implementing basic operations (add, remove, access).
  • Exception Handling: Master try, catch, finally, and throw blocks. Practice catching and handling common exceptions (e.g., ArrayIndexOutOfBoundsException, NullPointerException, NumberFormatException).
  • Debugging: Develop systematic debugging techniques: reading error messages carefully, using print statements strategically, stepping through code with a debugger (IDE), and isolating issues.
  • Practice FRQs: Work on FRQs involving 2D arrays, linked lists, exception handling, and complex debugging scenarios.

Step 7: Weeks 7–8: Review, Integration & Full-Length Practice

• Focus: Consolidate knowledge across all units, practice integrating concepts, and simulate exam conditions.
• Actions:
  • Comprehensive Review: Revisit all units, focusing on interconnections (e.g., how arrays relate to loops, how OOP concepts apply to data structures). Create summary sheets or flashcards.
  • Integrated FRQ Practice: Tackle FRQs that combine multiple concepts (e.g., OOP + arrays + recursion, exceptions + sorting).
  • Full-Length Practice Tests: Take timed, full-length practice exams (both MCQ and FRQ sections). Simulate the actual exam environment (quiet space, no notes, strict timing).
  • Analyze Mistakes: Meticulously review every practice test question you get wrong or are unsure about. Understand why you were wrong and how to avoid it next time.
