For coaching institutes, digitizing old physical question papers and PDF notes into online tests is a massive bottleneck. Data entry operators spend hours manually typing out math equations and chemistry formulas, costing time and money.
PrepLab’s AI PDF extraction reduces test creation time by 85% compared to manual typing, processing up to 100 math and chemistry questions in under 2 minutes. In this guide, we will show you exactly how to transform a static PDF into a fully digital mock test.
The Problem with Manual PDF Data Entry
Traditional test creation involves typing questions manually into a portal. When dealing with complex subjects like JEE Mathematics or NEET Chemistry, you encounter symbols and diagrams that are notoriously difficult to format correctly online.
- LaTeX math equations often break during copy-pasting
- Chemistry SMILES notations are rarely supported
- Data entry is expensive and prone to human errors
- Formatting takes longer than the actual test creation
How AI PDF Extraction Works
Instead of typing, modern platforms use AI vision models to 'read' the PDF just like a human teacher would. The AI identifies what is a question, what are the four options, and converts everything into a digital format automatically.
Step 1: Upload the PDF
Simply drag and drop your existing mock test paper into the PrepLab AI Canvas.
Step 2: AI Processing
The AI scans the document, intelligently separating questions, options, and recognizing complex formulas.
Step 3: Review and Publish
You get a digital preview of the questions. Simply assign the correct answers and publish the test directly to your student batches.
