Is NCERT Enough for IAT 2026?
✅ Biology: NCERT Class 11 & 12 covers approximately
85–90% of IAT Biology questions. Read every line including boxes and diagrams.
✅ Chemistry: NCERT covers approximately
70–75% of IAT Chemistry. Focus on inorganic reactions, organic mechanisms, and
environmental chemistry.
⚠️ Physics & Mathematics: NCERT provides the
conceptual base (~60–65%), but you need IAT previous year papers and assertion-reason practice
for complete preparation.
