Biohack by Parth Goyal is a strategically crafted biology revision tool designed specifically for NEET-UG aspirants, focusing on the powerful technique of active recall to enhance memory retention and exam performance. Authored by Parth Goyal, a NEET 2019 top scorer with an All India Rank of 223, the book transforms the NCERT Biology syllabus into an interactive format featuring fill-in-the-blanks, one-word answers, true/false questions, match-the-following, and diagram-based questions, allowing students to test their recall line-by-line and internalize key concepts effectively. This unique method replaces passive reading with direct engagement, helping students reinforce high-yield facts and critical NCERT lines that frequently appear in NEET exams. A standout feature is the inclusion of DigaQs—diagram-based questions—that train students to quickly and accurately interpret visuals, which is crucial given the image-based nature of many NEET Biology questions. The book follows the NCERT chapter flow for Class 11 and 12, ensuring seamless integration with existing study plans and allowing focused, topic-wise revision or full-syllabus practice. While Biohack is not a replacement for the NCERT textbook, it is an essential revision companion meant to be used after understanding the core content, offering a structured and efficient way to revisit and reinforce knowledge. It helps identify weak spots, promotes better long-term retention, and builds confidence by enabling consistent self-assessment. The active recall approach is grounded in proven cognitive science principles, making it far superior to rote memorization and passive note-taking. Available in both English and Hindi editions, Biohack also offers digital support in some versions through a mobile app, which provides extra question banks and flexibility for on-the-go learning. It is especially beneficial for self-study students, repeaters, and those in the final stages of NEET prep, where quick, high-impact revision is essential. By converting textbook lines into active exercises, Biohack ensures that students don’t just read but master the syllabus, gaining the ability to recall and apply information under exam pressure. In essence, Biohack is a result-oriented, smart-learning resource that empowers students to make the most of their biology preparation and gives them a competitive edge in one of India’s toughest medical entrance exams.
