The JEE Glossary in one minute
A free plain-English reference of 71 JEE terms. Every term gets a direct answer first, then key points, why it matters, where it is used in real decisions, common mistakes and FAQs — built for quick lookup and last-minute revision.
Three ways students use this glossary
- Decode a form or portal: every counselling acronym (OR-CR, PAF, CRL, seat type) has a direct answer you can act on immediately.
- Compare ranks honestly: the rank and score terms explain which number to compare against which cutoff, so shortlists stay realistic.
- Explain it to someone at home: each page is written to be read out in one minute — useful for parents who need the plain version.
