Biotechnology Eligibility Test 2021

Eligibility | Dates | Pattern | Syllabus

Last Updated on 12th October, 2021

The Department of Biotechnology along with the Ministry of Science & Technology and Government of India gives fellowships to biotechnology students as an award of DBT – Junior Research Fellowship (DBT-JRF) in Biotechnology every year by conducting national level Biotechnology Eligibility Test (BET). This exam is to encourage biotechnology students for pursuing doctoral research in research institution or universities across the country. The eligible students are selected by the Biotechnology Eligibility test (BET), which is now being coordinated by the National Centre for Cell Sciences.

Based on the performance of candidates in BET, two categories of merit lists are prepared – Category-I and Category-II. Candidates who are selected under category-I are eligible to avail fellowship under the programme. These are tenable at any university/institute in India where the selected candidate registers for PhD Programme.

Candidates selected under the Category-II are eligible to be appointed in any project that is sponsored by DBT and avail fellowship from the project equivalent to NET/GATE, subjected to selection through the institutional selection process. There will be no binding in Principal Investigators of DBT sponsored projects for selecting JRF for their project from Category-II list. Being selected in the Category-II will not entitle students for any fellowship from DBT-JRF programme.

BET Exam Pattern 2021

The paper is divided into two parts – part A and B. Part A consist of 50 multiple choice questions, and Part B consists of 150 questions out of which 50 questions need to be answered. For each right answer, candidates are awarded three marks, and there is no negative marking for any wrong answers. The time allotted for this paper is 180 minutes, and it is conducted in online mode. Candidates will be selected based on the computer-based, Biotechnology Eligibility Test (BET). A candidate can opt for any three centres of their choice from the options given in the application. No TA/DA will be allowable to any of the candidates for appearing for the test.

Pattern for BET
