Interleaved practice

Instead of blocking one A-Level Maths topic at a time, we mix questions across your 5 weakest topics in random order. This "interleaving" approach is well-established in the memory-and-learning literature (see Rohrer & Taylor, 2007; Bjork, 2011) as a more effective way to build durable retention than blocked practice, because your brain has to actively identify which method applies rather than repeat a single one.

How this works: We read your recent scores, find your 5 lowest-accuracy topics (min 2 attempts each), and hand-pick 10 mixed questions across them. Aim for a 25–30 minute session.

Why mix topics in A Level Maths practice?

In a topic exercise you know the method before you read the question: every question in the integration by parts exercise needs integration by parts. An exam paper does not tell you. A question on ∫ x e^2x dx and one on ∫ x e^x² dx look alike, but the first needs integration by parts and the second a substitution (or recognising the chain rule in reverse). Interleaved practice makes you decide which method to use, which is the step students most often get wrong under exam conditions.

How to use a session

Before you start each question, write down the method you will use and why. Check that choice against the mark scheme as well as the answer.

Keep the questions in the order given, even when the next one is on a topic you find hard.

When a topic keeps appearing in your mix, go back to its notes and worked examples, then return to mixed practice.
