Candidates need to review the GATE syllabus for the stream that they wish to appear. The syllabus defines the topics or subtopics that the candidates need to prepare for appearing in the examination. It’s a very important part of the examination as it helps the students know what they have to study.
This article will give you complete information regarding the GATE Biotechnology Syllabus 2023.

GATE is one of the most competitive examinations that needs complete focus and a good understanding of basic concepts. In order to clear the exam, the candidates must have a thorough preparation.
Every subject requires a keen understanding and practice. You must devote a good amount of time to every subject based on your comfort and knowledge. Before starting the preparations, you must create a timetable that covers all your subjects/topics.
Try to appear for as many mock tests as possible.
Good luck with your future!
