Is Biohack Enough for NEET Preparation
Many students ask Is Biohack book good for NEET?
The Biohack book is an excellent tool for revision and NCERT mastery, but it’s not sufficient as a standalone resource for NEET preparation. Here’s why:
Strengths for NEET
- Covers 100% of NCERT, which is critical since NEET biology is heavily NCERT-based
- Helps students avoid “silly mistakes” by focusing on tricky questions and common errors.
- Ideal for quick revision in the final months before NEET, ensuring retention of key facts.
Limitations
- Lacks the depth of practice questions needed for mastering complex or application-based problems.
- Does not replace the need for standard NCERT textbooks or additional resources like MTG, Arihant, or previous year question banks.
- Best used alongside other materials, such as NCERT Exemplar, coaching modules, or mock tests.
Recommendation: Use Biohack as a revision tool after thoroughly studying NCERT and practicing with other question banks. Combine it with PYQ books and mock tests for comprehensive NEET preparation.

To maximize the benefits of the Biohack book, follow these tips:
1.Complete NCERT First: Ensure you’ve read and understood the NCERT biology textbooks for Classes 11 and 12 before using Biohack. It’s designed for revision, not initial learning.
2.Use Active Recall: Engage with the true/false, fill-in-the-blanks, and one-word questions actively. Cover the answers, attempt them, and check for accuracy to reinforce memory.
3.Leverage Spaced Repetition: Revisit chapters at increasing intervals (e.g., after 1 day, 3 days, 1 week) to strengthen long-term retention.4.Practice Diagrams: Use the Diga.Qs (unlabeled diagrams) to master visual concepts, as diagrams are crucial in NEET.
5.Focus on PYQs: Pay attention to previous year questions and mnemonics to understand exam patterns and high-yield topics.
6.Supplement with the App: Download the Parth Goyal app to access the question bank included with the book for additional practice.
7.Schedule Regular Revision: Dedicate 30–60 minutes daily to Biohack, covering 2–3 chapters to complete the syllabus
