NBME-Style Exam Practice
Built for Your Shelf Exams

Most question banks show whether you were right. This simulator is built around what happens next: take realistic timed blocks, keep the original PDF source nearby, review missed questions with the reasoning pattern attached, and turn weak topics into focused practice instead of vague study lists.

Quick start
🎯

Authentic NBME Interface

Timed blocks, flagged questions, answer strikethrough, lab values, and source-page backup keep practice close to the way the exam actually feels.

📚

Practice That Targets the Gap

Launch focused blocks by system, task type, difficulty, or prior misses so review time goes toward the concepts that are actually costing points.

🔬

Mistakes Journal

Wrong answers become a study map: topic, tested skill, timing, answer changes, and repeat patterns all stay attached to the question.

AI Tutor When You Need It

Use deeper explanations, distractor breakdowns, and Anki-style takeaways after a block without making AI the center of every workflow.

Exam Simulator Guide

Upload a PDF. Let the app prepare it. Take the block.

The simulator is designed to feel simple on the surface. Most students only need to upload the question PDF, click Prepare exam, add the answer key if they have it, and begin. Advanced extraction tools stay hidden unless a PDF needs help.

The normal workflow

This is the path most users should follow.

1

Upload question PDF

Drop the question PDF onto the upload card. Readable PDFs process fastest. Scanned PDFs may trigger OCR automatically.

2

Prepare exam

The app cleans screen text, finds questions, preserves source pages, detects choices, and validates the block.

3

Add answer key

Upload the answer PDF or paste the key. The app checks whether the answer count matches the question count.

4

Take the block

Use the NBME style exam screen with timer, flags, notes, cross out, answer lock, and source PDF backup.

5

Review results

See score, missed questions, timing, flags, answer changes, mistake tags, and repeat weak areas.

What happens automatically

  • Removes repeated headers, footers, timer text, and watermarks when safe.
  • Repairs duplicate or split question blocks when possible.
  • Preserves original source PDF pages as backup for images, ECGs, tables, and exact wording.
  • Stores completed attempts locally for trend tracking and review.

AI stays optional

Core review and analytics work without needing an AI explanation. Use deep dives when a question needs extra reasoning support.

If a PDF does not work

The app should guide the user with simple fixes before showing technical extraction details.

No selectable text

The PDF is probably scanned. Click Try OCR, or run OCR in Adobe Acrobat and upload the searchable version.

Question count is off

Use Review problem questions. Only use Continue anyway if the user accepts a partial block.

Answer key is not detected

Paste the answer key in a simple format like Item 1: C or 1.c. Explanation PDFs are supported when the pattern is clear.

Images or tables matter

Use Show original PDF page during the exam. The clean question text is for readability, while the source page is the fidelity backup.

Best rescue prompt for scanned question PDFs

Convert this exam PDF into clean plain text for an exam simulator. Rules: 1. Preserve every question exactly. 2. Keep each question separated. 3. Keep answer choices clearly labeled A, B, C, D, E. 4. Do not answer the questions. 5. Remove page headers, page footers, timer text, and watermarks only if they are not part of the question. 6. Preserve matching sets, lab tables, image references, and response options clearly. 7. Output only the cleaned exam text.

Backup and restore

Use this before clearing browser data, switching devices, or making major changes.

Cleanup tools

These tools protect analytics while reducing storage use. Export a backup before deleting anything.

Deleting extracted text means the original PDF may need to be reuploaded later. Excluding an attempt is safer than deleting it if you only want to protect analytics.

This extraction looks like it may only contain headers, page numbers, or screen clipping text instead of real questions. That usually means the PDF pages are images. Use OCR to read the visible question text. OCR can take several minutes for a full 50 question block. For best results, keep this browser tab open while it runs.

Confirm form type
The app detects the form first, then asks you to confirm before building the exam.
Detection will appear here after extraction.
Confirm the detected form type. CMS should have 50 questions. NBME should have 200 questions total.
