IGCSE, IB and A-Level Study Guides

The best Digital SAT practice is free and official: Bluebook's adaptive full-length tests and Official SAT Practice on Khan Academy, and how to use both.

Next SAT after 7 Nov: 5 December 2026, register by 20 November. Then 6 March, 1 May and 5 June 2027, with every deadline and score release date.

The Digital SAT gives you 12 geometry formulas — but nothing for algebra, advanced math or data analysis (~85% of questions). Here's what to memorise.

A perfect 1600 means 800 in both sections. How the adaptive test affects your ceiling, how many questions you can miss, and how to chase the top score.

A superscore combines your best section scores across multiple SAT sittings. How it works, which colleges superscore, and how it differs from Score Choice.

How A-Levels are graded: the A*–E scale, what counts as a pass, how UMS turns marks into grades, and the A* rule most students miss. Worked example.

Best A-Level subject combinations for medicine, engineering and law: which subjects are required, which keep doors open, and which to avoid.

How many A-Levels should you take? Three is the standard and most university offers are built on it. When a fourth actually helps, and when it backfires.

A-Level retakes explained: November, January and June resit sessions, single-unit resits on Edexcel vs whole stages on Cambridge, and which grade counts.

Investigating, Developing, Creating and Evaluating — the same four criteria across visual arts, music, drama and dance.

Only one of the four criteria is assessed in performance, which is why strong athletes can score below strong planners.

Listening, Reading, Speaking and Writing are equally weighted — so the weakest skill sets the ceiling.

How many times can you take the SAT? There is no official limit, but 2 to 3 sittings is ideal. How retakes, Score Choice and superscoring really work.

When should you take the SAT? Most students sit it in Grade 11 and retake in Grade 12. How to pick a 2027 test date around your prep and applications.
