How much is The s-block elements 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. The s-block elements carries 0.0 of 100 Chemistry 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. The s-block elements 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.
