Spaced repetition works by reviewing material right around the point you'd otherwise start to forget it, rather than reviewing it repeatedly in a single sitting. Applied to a question bank, this changes what you should do with questions you get wrong.
A missed question isn't finished when you read the rationale
Reading an explanation creates a feeling of understanding that fades quickly. Flagging missed questions for a second attempt a few days later — not immediately — tests whether the concept actually stuck.
Mix topics instead of blocking them
Working through one topic at a time feels productive, but interleaving topics forces you to first identify what a question is even asking about, which is closer to what exam day actually requires.
Let your weak-area report set the review queue
Instead of manually tracking which questions to revisit, use topic-level accuracy reporting to decide which subject gets a second pass this week, and let this week's report change next week's plan.
