Chemistry should fund your 300. Physical still ~50% of Chem tags; Organic share climbed toward ~38% by 2026. Distinct issues: numerical process slips in Physical, mechanism-memory without GOC logic in Organic, and NCERT fade in Inorganic.

Top 3 issues + solutions

Issue 01critical12–22 of Chem 100

Physical numericals: method known, answer wrong

Physical Chemistry for 300 is a numerical machine. Most lost marks are process slips: wrong system, sign of work, mole fraction vs molality, missing units — not missing theory.

How to fix it

Physical Chemistry for 300 is a numerical machine. Most lost marks are process slips: wrong system, sign of work, mole fraction vs molality, missing units — not missing theory.

How it looks in the paper

Irreversible isothermal compression work minimisation
Vapour composition y_B from Raoult
Electrochem / equilibrium numericals

Symptom

Thermo/equilib/electrochem — setup correct, mole fraction/sign/unit fails.

Root cause

Speed practice without a fixed numerical audit (system, sign, moles, final unit).

Issue 02high10–16

Organic rising — still treated as last-month syllabus

Organic share rose sharply toward 2026. Treating it as a last-month memory subject is a 300 plan failure. You need GOC logic + reaction maps + NCERT end chapters (biomolecules/polymers/practical).
