LabVerse is free to use, with no login or account needed. Here's what each part of the app does.
Tick one or more of the seven subjects, or tap "Select All Subjects." Only questions from your selected subjects will appear in your challenge.
Choose how many questions you want, based on how many are available in your current selection — including an "All Questions" option. The note under the Start button shows how many fresh (not-yet-seen) questions remain in your selection.
Relaxed (90 sec), Standard (60 sec), or Exam (45 sec) sets your overall pace. Your total time budget for the whole challenge is questions × seconds-per-question, shown as a single countdown clock during the challenge — it isn't a separate timer that resets for every question. If the clock reaches zero, any unanswered questions are automatically marked skipped and your results are shown.
When Exam Scoring is on: +1 for each correct answer, −0.25 for each wrong answer (skipped questions score 0 either way). Turn it off to score only +1 per correct answer with no penalty for wrong ones.
Tap an option to answer, or tap Skip. Either way, the correct answer and explanation (when available) are shown immediately, then tap Next to continue. If you spot a problem with a question, use "Report an issue with this question" underneath it to send a quick note.
After your last question, you'll see how many you attempted, got correct/wrong, your score, time taken, a performance message, and a subject-by-subject breakdown. From there you can review your answers question-by-question or start a new challenge.
LabVerse remembers which questions you've already seen on this device, so new challenges favor ones you haven't practiced yet. As soon as you've seen some questions in a selection, a "Reset & Start Fresh" option appears if you want to start that selection over from scratch — and once you've seen everything in it, resetting is the only way to see those questions again.
Progress is saved on this device/browser only — clearing site data or switching devices will reset it.
