OCR GCSE Computer Science J277 Programming Bootcamp: 30-Day Python & Pseudocode, 150 Tasks + Answers

OCR GCSE Computer Science J277 Programming Bootcamp: 30-Day Python & Pseudocode Challenge

A complete, classroom-ready programming programme for OCR J277: 30 days, 5 tasks a day, 150 numbered tasks (001–150), with full answers, marking guidance and progress trackers. It goes beyond Python syntax and builds the skills needed for J277/02 Section B: designing, writing, testing and refining programs.

What students practise

Python and OCR-style pseudocode, including translating both ways
Variables, data types, input/output, arithmetic and strings
Selection, Boolean logic (AND/OR/NOT) and boundary conditions
FOR and WHILE loops, nested loops, counters, accumulators and sentinel values
Lists/arrays, searching, filtering, functions and decomposition
Trace tables, debugging (syntax, logic and runtime errors), validation and authentication
Test plans with normal, boundary, invalid and extreme data
Binary search and bubble sort tracing, plus a 10-stage Day 30 final challenge (Design, Write, Test, Refine)

Six progressive phases

Programming Foundations (Days 1–5)
Selection and Decision Making (Days 6–10)
Iteration and Trace Tables (Days 11–15)
Data, Strings, Lists and Functions (Days 16–20)
Robust Programming and Debugging (Days 21–25)
Exam and Grade 9 Mastery (Days 26–30)

Every day includes: a learning objective, quick recall, skill builder, worked example, five graded tasks (Level 1 Foundation to Level 5 Grade 9) with workspace boxes, full daily answers, common mistakes, an exam connection and a self-rating.

What’s in the pack (8 editable Word files, 300+ A4 pages)

Front matter: teacher introduction, how-to guide, 20-mark diagnostic, Debugging Checklist, Testing and Trace Table systems, command word guide, student checklist
Parts 1–6: all 30 days, with a 20-mark checkpoint after every five days
Back matter: teacher answer book, 16-item misconception bank, 30-day and 150-task trackers (with spreadsheet formulas), skills mastery matrix, personal best page, 15-task Retry Bank, final performance report, completion certificate, teacher intervention guide

Ideal for: Year 10–11 OCR J277 students, intervention and catch-up groups, homework, holiday bootcamps, independent revision, private candidates and home educators.
