I understand the importance of effective exam preparation for your students , and I am here to provide you with valuable materials to help you excel in your students IGCSE Computer Science exams with nearly 300 questions and Answers.
What’s Included:
IGCSE CS 0478 Paper 1 and 2 Revision Exams (2024): nearly 500 questions and Answer from chapter 1/2/3/4/5/6/7/8
These carefully curated revision exams are designed to simulate the actual IGCSE Computer Science Paper 1 and Paper 2 exams for 2024. They include a wide range of questions covering key topics and concepts outlined in the syllabus, ensuring that you are well-prepared for the real assessment.
2. Bonus Past Exams Data Analysis for Paper 1 (2023):
In addition to the 2024 revision exams, I am delighted to provide you with a bonus: a detailed data analysis of the IGCSE Computer Science Paper 1 from 2023 exams. This insightful analysis will help your students understand the trends in previous exams, identify common question types, and refine your students exam-taking strategies. It’s an invaluable tool for enhancing your students performance in the upcoming Paper 1and 2 exam.
How to Make the Most of These Resources:
Make sure your students start theirs revision early to ensure a thorough understanding of the topics.
Use all past exams revision as practice papers to test students knowledge and time management skills.
Dive into the bonus data analysis to gain insights into the Paper 1 exam trends.
Collaborate with your students and make them work in peers to discuss challenging concepts and problem-solving strategies.
Make sure to ask your students to stay organized, create a study schedule, and to stay consistent in theirs efforts.
I hope that these resources will empower your students success in the IGCSE Computer Science exams. Remember that to advice your students that consistent practice and a deep understanding of the subject matter are key to achieving excellent results.
Best of luck to prepare your students for the IGCSE exams!

Blockly programming for Year 6 and 7
Blockly is a client-side library for the programming language JavaScript for creating block-based visual programming languages and editors. A project of Google, it is free and open-source software released under the Apache License 2.0. It typically runs in a web browser, and visually resembles the language Scratch.

For all Teacher attached a student project for you attention:
Please before you solve any pre-release material for students. It is better to let them try to solve it first.
please give this project to your student for a period of a month therefore you can measure students progress and attainment.
IGCSE Pre- release material for Computer Science paper 2 - Student Project
Attached the Pre-release material for paper 2 exams , Please ask the students to open the PDF and watch the video and it will give students a starting point how to solve task 1/2/3 for this year exam. Thank you
But before that. student should start attempting pre-release paper 2 for last year May/June 2021, Please ask the student to go straight to slide 11 and do the last year exam paper 2 May/June 2021 , Students will find the questions/answers and the python programming code for task 1 / 2 and 3 .
