GATE 2018 Syllabus for Biotechnology (BT)

Last Updated - August 19, 2017

Biotechnology is covered in various engineering branches like Bioinformatics, Biomedical engineering and in biotechnology itself. Exam pattern for GATE Biotechnology is same as that of Biomedical and Bioinformatics. GATE will be conducted in online mode as a Computer Based Test and will have multiple-choice questions. Candidates will be given 3 hours to complete the exam. 

  • GATE 2018 is scheduled for February 03, 04, 10 and 11, 2018. 
  • GATE Exam Pattern consists of 3 sections namely General Aptitude, Engineering Mathematics and specific subject of the paper.
  • A proper GATE Paper Analysis must be done by the candidates about the sections are covered in the exams and must exclude the unworthy sections.
  • GATE Biotechnology Syllabus will include Engineering Mathematics, Biotechnology, Recombinant DNA Technology, Plant and Animal Biotechnology and Bioprocess Engineering and Process Biotechnology.

GATE Exam Pattern will consist of total 65 questions and a candidate can score maximum 100 marks in the exam. No marks will be deducted for any wrong answer. GATE will be held in 2 shifts (Morning and Afternoon).

It is very important for a candidate to know the GATE 2017 Exam Pattern so that he or she can know the type and number of questions asked in the exam.

Sakshi Garg Expert

Hi Abhishek, GATE (Graduate Aptitude Test in Engineering) is a national level test for admission to M.Tech/ Ph.D. and other Government Scholarships/Assistantships in the field of engineering and technology. So you can not fill this exam for MBA. But you can apply for MBA by filling the CAT, XAT, CMAT, GMAT entrance exam.
