    • Revise from your error list: formulas, named reactions, Acts and their years.

Mistakes that cost marks

5 traps seen in the real papers
  • Treating Paper I as filler: it is 150 of the 450 marks.
  • Chemistry: skipping the long Forensic Science syllabus (instrumental analysis, NDPS drugs, explosives, toxicology).
  • Biology: studying only your own degree; seven sections are printed and cell biology, genetics and immunology recur.
  • Ignoring the named Acts: NDPS, Drugs and Cosmetics, Excise, Explosives, Explosive Substances, Wildlife (Protection) Act 1972.
  • Applying without checking the colour-blindness rule and the five-year laboratory experience note.
