Reviewed October 2026
Every file read. Every topic where Cambridge puts it.
All three packs were taken apart and rebuilt this term, file by file, against the syllabus you will actually sit.
Checked against the current syllabus
Every ZAK file was read in full and corrected: content, Cambridge wording and command words, spelling and layout.
Numbered the way Cambridge numbers it
Folders, files and page headers follow the current syllabus sections, so a topic in the pack is the same topic in the syllabus and on the website.
Gaps filled
New notes where a section had none, assignments for every syllabus section, a test for every topic and new mocks — four each for AS and A2 — all with full answers.
A mark scheme for every test
Class tests, monthly tests, mid-terms and mocks all come with their mark schemes, and O Level mocks that repeated each other were rewritten with new questions.
Class boards corrected
Where a handwritten board had a slip, a typed Corrections page now sits at the end of that file.
Cambridge archive completed
Missing papers, mark schemes, examiner reports and grade thresholds added and sorted by paper, year and session.

How to use it
Learn it. Practise it. Mark yourself.
The Pack Guide in 0. START HERE walks you through this for every topic, and the Statometer tells you which topics to put first.
1
Learn it
Open the topic's notes, then watch its lecture. Use the class boards for the hard parts.
2
Practise it
Do the topic's assignment, then its topical past-paper questions — Banker and Core topics first.
3
Mark yourself
Check against the answers or Cambridge's mark scheme, redo what lost marks, then sit the topic's test and later a timed mock.

About ZAKATHONQuestions
Before you ask.
I'm taking IGCSE 0478, not O Level 2210. Is this pack for me?
Yes. 2210 and 0478 are one course: the same ten topics, the same two papers and many identical questions. The pack holds both codes' papers, mark schemes, examiner reports and grade thresholds side by side.
Which syllabus does the pack follow?
The current one, section by section: the 2026–2028 O Level / IGCSE syllabus and the 2027–2029 9618 syllabus. The O Level pack also files the 2029–2031 edition's syllabus and specimen papers in their own folders, ready for students sitting it.
I'm doing the full A Level in one go. Which pack do I need?
Both the AS and the A2 pack. They are laid out the same way, so the two drives work as one.
Does the pack replace the website?
No — they work together. The website stays free forever, with no ads. The pack is the structured library you can follow offline; the Website Companion in each pack links every topic to its free topic page, quiz, flashcards, past-paper questions and Statometer.
How is it kept up to date?
New papers, mark schemes and examiner reports are added after every exam session, and ZAK's material is updated as he teaches. The whole pack was last reviewed in October 2026.
How do I open it?
It is a shared cloud drive (OneDrive or Google Drive) opened with your own email address. It works on a phone, tablet or laptop and there is nothing to install. Start with the Pack Guide in 0. START HERE.
Can I share it with a friend?
No. A Success Pack is a personal licence for one student, as the Tuition terms explain. Sharing the drive ends the access.
Something else? or message the admissions team.
