This quiz builder gives you four controls: topic, difficulty, question count, and timer mode. Each one changes the feel of the session in a specific way, and the right combination depends on how much time you have and what you are trying to rehearse. The short version: start with a 20-question Medium quiz across all topics, then use the result to decide where to drill deeper.
Choosing "all topics" is closer to real exam conditions — the question order forces you to switch context, which is exactly the skill the NSCT tests. Picking a single topic is the right call when you already know your weak spot and want to hammer it until it is solid. A common mistake is to always drill single topics; that builds false confidence because your brain never has to discriminate between concepts.
The per-question timer is the closest simulation of NSCT pressure and the best diagnostic for whether you are actually ready. Total timer is gentler but still rehearses pacing. Unlimited is for learning mode, not assessment mode — use it when you are still studying a topic. For review, choose instant review when you are learning (you see the answer after every question), and end-of-quiz review when you are practicing under exam conditions (you only see results at the end, which is more realistic).
