CEFR levels are not abstract grades here — each one is a concrete IGCSE skill. This is what climbing the ladder actually buys you.
Read a question the way the exam means it. Understand what "state", "calculate" and "describe" are asking, so you stop losing marks you actually knew — the language stops getting in the way of the subject.
Write answers that do what the command word demands. Explain a process, compare two ideas, justify a conclusion — the structured academic English that turns a 2-mark answer into a 5-mark one across every subject.
The top of the ladder: argue, analyse and craft with the range and control that First Language English (0500) rewards. Fluent academic writing that reads like a native — and scores like one.

It is the English you need to study IGCSE subjects in English — reading Science and Maths questions accurately, understanding command words like "explain" and "compare", and writing structured answers. It is different from conversational English: it is the language of the exam itself, and it decides marks in every subject.
B1 is the floor for following instructions in Science and Maths; B2 is where you master command words for subjects like Biology and History; C1 is where you write fluent, high-scoring First Language English essays. The 2-minute vocabulary check shows which rung your vocabulary is on.
IELTS is a general proficiency test; this is built around the academic English IGCSE actually uses — the command words, question stems and subject register of Cambridge exams. If your goal is to succeed in IGCSE subjects taught in English, this trains exactly that.
