Expert-authored questions, each independently checked for a correct answer key and tagged deeply enough to tell you exactly where every student stands. Size your bank, pick a quality tier, and see a real per-question estimate.
Harder questions cost more to produce β a JEE-Advanced problem takes far more work to author and verify correctly than a straight recall question, so pricing is per difficulty tier. Set the counts for your bank and the total updates live.
Estimates are indicative and assume a mostly-text bank. Question sets that are heavy in figures, graphs or long comprehension passages run higher, since each figure has to be read and understood before it can be tagged. Volume arrangements for banks above 50,000 questions are available β talk to us for a formal quote.
A 30-tag-per-chapter scheme is a solid start β it can flag which chapters a student is weak in. But a chapter is a big place. The value of deep tagging is that it keeps going: past the chapter, past the topic, down to the exact micro-skill and the specific misconception behind a wrong answer β and it keeps that picture current as the student changes.
"Aarav is weak in Human Physiology."
True, but it covers a hundred sub-skills. A teacher still has to re-teach the whole chapter and hope the real gap is in there somewhere.
Aarav knows his hormones. He only trips when a question asks him to link a feedback loop across two organs β and each time, his wrong answer reverses the feedback direction. He's slow and unsure on just those. The fix is one sharp concept, not a whole chapter.
Same student, same test. The 30-tag view sends a class of forty into a full-chapter revision. The deep view hands each of the forty a two-minute fix aimed at their own exact gap β and updates the moment they improve. That is the difference between grading a bank of questions and understanding a student.
Because the companion reads the same fine-grained picture, it doesn't start from zero every time. It skips what the student already knows and teaches the one thing in the way β in the student's own words, at the exact moment they need it. Here's the same wrong answer, handled three ways.
The difference isn't a smarter answer β it's a smarter starting point. A generic assistant answers the question. The companion answers the student: it knows their history, targets the exact gap, teaches only that, and marks the skill as improving once they get it β so the next nudge is already aimed somewhere new.
To tag a question deeply and guarantee its answer key, the work has to actually solve it. A JEE-Advanced integral demands minutes of careful reasoning; a biology recall item is nearly instant. That gap β often 15β20Γ β is exactly why the estimator prices per tier rather than one flat rate.
