Prioritise reducing vs non-reducing sugar questions. This is the single most-repeated question type. Know that sucrose is the only common non-reducing disaccharide; all others (glucose, fructose, lactose, maltose) are reducing. The reason always involves the anomeric carbon.

Memorise vitamin–disease pairs as a table, not as a list. NEET often gives 4 options each with a vitamin–disease pair and asks which is correctly matched. Learn both the chemical name and the disease.

Distinguish denaturation from hydrolysis clearly. At least one MCQ per 2–3 years asks what happens to "primary structure" during denaturation. The answer is always: primary structure (peptide bonds) is NOT disrupted.

For nucleic acids, focus on H-bond numbers. "A–T = 2, G–C = 3" is directly tested. Also know the consequence: higher G–C content → higher melting temperature of DNA.

Use process of elimination for vitamin questions. Fat-soluble vitamins = ADEK. If the option lists any B vitamin or C as fat-soluble, eliminate it immediately.

Link glycosidic linkage to reducing character. Questions may give a new sugar with a linkage description and ask if it is reducing. Check: is the anomeric carbon (C1 for aldoses, C2 for fructose) involved in the bond? If yes → non-reducing.

Do not skip polysaccharide linkages. $\alpha$-1,4 vs $\beta$-1,4 is directly tested in the context of digestibility. Cellulose = $\beta$-1,4 = indigestible = dietary fibre.

Protein secondary structure H-bond direction. $\alpha$-helix: H-bonds are intramolecular (within the same chain). $\beta$-sheet: H-bonds are intermolecular (between adjacent chains). NEET distractors swap these.

Allocate 1.5–2 minutes per biomolecule question. These are mostly recall-based and should be solved in under 90 seconds if well-prepared. Do not spend more than 2 minutes on any single question.

Glycogen vs amylopectin trap. Both have $\alpha$-1,4 + $\alpha$-1,6 linkages. The difference: glycogen (animal, liver/muscle) is MORE branched than amylopectin (plant). If asked which is more branched, answer: glycogen.
