cbt4jee-33.2.5

CBT4JEE v33.2.5 - FIITJEE AITS Paper Processor & Practice Platform

What's New in v33.2.5

Processor Improvements

• Subject Symmetry Enforcement: All 3 subjects (Physics, Chemistry, Mathematics) now have guaranteed equal question counts per section
• Marking Scheme Symmetry: Corresponding questions across subjects enforce consistent (correct, negative) marks via majority vote
• Improved Answer Key Parsing: Better handling of old papers with table-format and inline-format answer keys
• N/A Answer Inference: Missing answers filled using cross-subject symmetry patterns
• Glitched Option Filtering: Single non-A-D letters (F, J, X) from OCR are automatically rejected
• Photo-PDF Detection: Scanned/photo PDFs are automatically detected and skipped (< 5 chars/page average)
• Subject Planner Detection: Short PDFs (< 3 pages) are automatically skipped
• Paragraph Crop Improvement: Better handling of paragraph/comprehension questions spanning page boundaries
• Info-Box False Positive Fix: FIITJEE "Useful Data" reference boxes properly excluded from question crops

Batch Processing

• Robust Solution Matching: Handles inconsistent naming (sol before/after QP, various naming conventions)
• Sequential Processing: Papers processed one-by-one to avoid memory issues
• Validation: Post-processing validates question count symmetry and marking scheme consistency

Supported Papers

• FIITJEE AITS 2013-2025 (JEE Advanced + JEE Mains)
• Currently processed: 61 papers from 2013-2015
• More papers being processed and added
