Preparation Master Tips for HPPSC Scientific Officer (NDPS) Exam 2026

1. Start with the official syllabus PDF: Map each of the 12 units against your existing knowledge to identify weak areas early.
2. Prepare Part-I and Part-II as separate blocks: Part-I is forensic-science-heavy while Part-II is chemistry-and-pharmacology-heavy. Do not mix topics across parts.
3. Focus on principles and applications of instrumental methods: Microscopy, spectroscopy, chromatography appear across multiple units. Learn principle, instrumentation, and application for each technique.
4. Practice descriptive answer writing within time limits: The SAT is a 3-hour descriptive paper, not objective. Write mock answers to improve speed and clarity.
5. Revise referenced laws: BNS, BNSS, BSA 2023, IT Act 2000, POCSO Act, NDPS Act, MVA Act – study these alongside technical topics.
6. Maintain a running note of drug/alkaloid names and extraction methods: Units VIII and XI have detailed lists that are easy to mix up; use flashcards or mnemonics.

Summary of Minimum Qualifying Marks

The official notification does not explicitly state minimum qualifying marks for the SAT. However, candidates must secure a score above the cutoff determined by the commission based on merit and number of vacancies. Typically, for Group-B posts in HPPSC, the qualifying marks may be around 40-50% for general category and relaxed for reserved categories. For exact cutoff criteria, refer to the official advertisement or future updates on hppsc.hp.gov.in.
