How much is Definite Integrals worth in JEE Main?

4.5 marks out of 100 in the Mathematics section, measured from this chapter's real share of tagged previous-year JEE Main questions — not an editor's opinion.

How many practice questions does ViJEEta have for Definite Integrals?

1523 exam-grade questions (738 from the curated premium pool: human-written test-series anchors and their calibrated variants), plus 41 real PYQs kept separate.

How does ViJEEta decide I've mastered Definite Integrals?

At least 3 answered questions in the chapter, a guessing-corrected IRT true score at a conservative ability estimate, and 'mastered' (≥0.80) is reachable only through tests — book work caps at 0.60 and unproctored practice at 0.75.

How much is Definite Integrals actually worth?

Every chapter's weight on ViJEEta is derived, not asserted: we tag every previous-year JEE Main question to its chapter, and a chapter's weight is its real share of those papers. Definite Integrals carries 4.5 of 100 Mathematics marks. Your readiness /300 uses exactly this weight — so an hour spent here moves your score by what the exam actually pays for it.

chapter_weight = tagged_PYQs(chapter) ÷ Σ tagged_PYQs(subject) readiness_contribution = 100 × chapter_weight × your_mastery

What does "mastered" mean here — honestly?

ViJEEta refuses to print a number it hasn't measured. Definite Integrals shows "—" until you've answered at least 3 questions in it. After that, mastery is a guessing-corrected IRT true score at a conservative ability estimate over the chapter's real item difficulties — a blind 25% MCQ guess earns zero. Reading theory caps evidence at 0.60, unproctored practice at 0.75; "mastered" (≥0.80) is reachable only through tests. That's why the number is worth trusting.
