About this app

Pass the medical laboratory scientist board exam with confidence. Med Lab Scientist Prep gives you 1,221 board-style MLS practice questions — and every single one comes with a detailed explanation you can actually learn from.

Is this how you finally pass? Most MLS exam prep apps recycle a shallow pool of questions, repeat the same items after ten taps, and ship wrong answer keys. This app is built on the opposite promise: accuracy and depth. Every practice question explains why the correct answer is right AND why each wrong option is wrong — so you understand the reasoning, not just memorize a letter.

WHAT'S INSIDE
- 1,221 board-style practice questions across all 7 exam domains.
- Learn visually: 200 real microscopy images — blood-cell morphology, Gram stains, acid-fast bacilli, parasite ova & larvae, malaria
smears, and urine crystals & casts — in quiz questions, flashcards, AND study notes.
- A detailed explanation on every question, including the rationale for each wrong choice.
- 3-stage learning on every topic: Skim the key points, drill swipeable Flashcards, then test yourself with a Quiz. All 34 topics
include all three stages.
- 37 concise study notes and 638 flashcards covering every topic.
- Full-length timed mock exam: 100 questions in 150 minutes, weighted to mirror the real domain blueprint.
- Missed-question review notebook so you can attack your weak spots.
- Exam-date study planner and a "today's roadmap" that tells you exactly what to review next.
- Works 100% offline.
- Light and dark mode.

COVERS ALL 7 BOARD DOMAINS
Blood Banking, Clinical Chemistry, Hematology, Microbiology, Immunology, Urinalysis & Body Fluids, and Laboratory Operations.

New questions are added every month at no extra cost.
