Practice SBA by topic
1,200+ SBA questions across all 15 body systems. Pick a topic to focus on.
Single Best Answer (SBA) is the most common NCLEX® format. You read a clinical scenario and choose the one best answer from four options. Every option is clinically plausible, so you need to evaluate each one carefully rather than looking for obvious wrong answers.
How many SBA questions are on the NCLEX®?
SBA makes up the majority of NCLEX® questions. The exam is 85–150 items and most are SBA format, mixed with SATA, BowTie, and Case Studies. The exact mix depends on the computer adaptive algorithm.
How does StudyWithLily make SBA questions harder than other apps?
Every SBA question has four clinically plausible options, not three throwaway answers and one correct one. Wrong answers reflect real misconceptions nursing students have. Difficulty scales from recall (Bloom’s 1) to evaluation (Bloom’s 5), and Lily adjusts in real time based on your answers.
