Why Students Choose Gawa Hub
Built specifically for the Cambridge IGCSE syllabus, not adapted from generic science content. Every guide is structured the way the exam is structured.
Syllabus-Matched Structure
Every topic maps directly to the official 0625 and 0620 syllabus codes, so nothing you study is off-target and nothing you need is missing.
Exam-Style Practice
Practice questions are written in genuine Cambridge command-word style — "state," "explain," "calculate" — so exam day never feels unfamiliar.
Instant Marking
Interactive practice exams give you a score and topic breakdown the moment you finish, so you know exactly where to focus next.
Formula Sheets Built In
Every physics topic links back to a clean, printable formula reference, so you're never hunting through pages of notes mid-problem.
Visual-First Explanations
Diagrams and worked examples come before dense text, because most IGCSE marks are lost on application, not definitions.
Free & Always Accessible
No sign-up walls, no paywalls on core content. Gawa Hub exists so a good study guide isn't gated behind a subscription.
How It Works
Three steps between you and exam-ready confidence.
01
Pick Your Subject
Choose Physics 0625 or Chemistry 0620 and land straight on a full topic map of the syllabus.
02
Study Topic by Topic
Work through notes, diagrams, and worked examples at your own pace, in the order the exam expects.
03
Test & Review
Sit the interactive practice exam, get instant marking, and revisit exactly the topics that need work.
What Students Say
Real feedback from IGCSE students using Gawa Hub to prepare.
★★★★★
The formula sheet alone saved me hours before my physics exam. Everything was organized exactly how the paper is structured.
★★★★★
I finally understood mole calculations after going through the chemistry topic notes. The worked examples make the difference.
★★★★★
The practice exam marking showed me my weak topics instantly. I went from guessing to actually knowing what to revise.
★★★★★
Nuclear physics finally clicked once I saw the diagrams here. Way clearer than my textbook's wall of text.
★★★★★
I used the topic list to plan my whole revision schedule two weeks before the exam. Genuinely well organized.
★★★★★
Free, no login, no ads blocking the content. Just the notes I actually needed, laid out properly.
Frequently Asked Questions
Everything you need to know before you start studying.
Yes. The core study guides, notes, and practice exams for both Physics 0625 and Chemistry 0620 are completely free — no account or payment required.
Gawa Hub currently covers Cambridge IGCSE Physics (0625) and Cambridge IGCSE Chemistry (0620), based on the 2026–2028 syllabus.
The interactive practice exams mark your answers instantly and break down your performance by topic, so you can see exactly where to focus your revision.
Both. The notes are written to stand on their own for self-study, but they also work well as a structured review alongside classroom teaching.
Gawa Hub was created by Professor Gawa, a Cambridge IGCSE specialist, to make thorough, exam-aligned study material freely accessible to students.
Content is reviewed against the latest Cambridge syllabus each cycle, currently the 2026–2028 specification, so topics stay accurate as the syllabus evolves.
Yes. The whole site, including the practice exams and topic notes, is built to work on phones and tablets as well as desktop.
Not yet. Gawa Hub currently focuses entirely on Physics 0625 and Chemistry 0620 so both subjects get full, deep coverage rather than being spread thin.
