How Acrolly Analyses JEE PYQs

Source corpus

Reports aggregate rows from acrolly.question_bank. At snapshot time:

• JEE Advanced: 1086 questions, 22 papers, 2016–2026
• JEE Main: 6801 questions, 82 sessions, 2023–2026

Advanced filter: reference ~ '^JEE_ADVANCED_[0-9]{4}_PAPER' AND reference NOT ILIKE '%MOCK%' AND reference NOT ILIKE '%CHAPTER%'

Main filter: reference ~ '^JEE_MAINS_[0-9]{4}_' AND reference NOT ILIKE '%MOCK%'

Grouping rules

(subject, chapter) — Thermodynamics exists in both Physics and Chemistry

Unit filters use ai_stream (e.g. Organic Chemistry, Mechanics, Calculus).

Difficulty scale

0–100 integer difficulty_level

• Main: Easy 0–49, Medium 50–64, Hard 65–79, Very hard 80–100
• Advanced: Medium 0–64, Hard 65–79, Very hard 80–100 (scores cluster high; almost no Easy band)

Question types

• mcq_single_correct → Single correct
• mcq_multiple_correct → Multiple correct
• integer → Integer / numerical
• matching → Matching
• paragraph_mcq → Paragraph MCQ
• paragraph_integer → Paragraph integer
• reasoning → Assertion–reason

Integer / numerical is a response format, not a claim that the item is purely computational.

What we do not claim

• Official NTA weightage or future paper predictions
• Calculation-complexity or conceptual-vs-computational scores (not stored)
• That every official Main shift is present in the bank

Figures reflect historical question distribution in Acrolly's tagged PYQ bank. They are not a prediction of future papers.
