GATE Biotechnology syllabus online tests books

GATE Biotechnology paper overview

Biotechnology is relatively new branch of Engineering. It is perceived to be growing branch on Engineering in future.Candidates with BTECH or BE in Biotechnology can apply for this paper. I have written separate article on eligibility criteria and other details of GATE Exams (post link).

You can read that post for details on eligibility criteria. You can also post your questions related to the exam there as well.In this article I will cover below points related to GATE Biotechnology paper

GATE Biotechnology paper statistics

Below statistics will help you get important insight about the exams.So lets see some interesting facts about this paper

  1. Number of candidates registered for the exam – 11,000(approx)
  2. Number of candidates appeared for the exam – 9,000(approx)
  3. Number of qualified candidates – 1936
  4. Percentage of candidates qualified – 21.5% (approx)
  5. Maximum marks out of 100 – 64.33
  6. Minimum marks out of 100 – 18
  7. Average marks – 31.35
  8. Standard Deviation – 6.88

The selection rate in Biotechnology paper is higher than that of many other papers. This is good news for candidates.However the maximum marks is one of the lowest.This means it is tough to get good marks but it is easy to pass the exams.

The average marks is around 31 marks.This means if you score more than 50 marks then you will get good marks.While planning and preparing for the exams you should keep this fact in mind.There is no point planning to score 100 marks. If you plan to study everything then quality will degrade.

You can plan the section you should focus on and get you marks close to 70 then it is fine. The quality of preparation should be good.You should be able to answer all questions or most questions from that section.

GATE Biotechnology Recommended Book

Your text books can be used as study material.But some students want dedicated book for exams.Dedicated books help them by providing topics in concise form.Out of the books available in market you can follow below books.I have mentioned few options that will help you make decision.

I have mentioned the books in order of preference. You can read the details about the books and then decide which one you want to opt for.

Book 1

The book is divided into three sections General Aptitude, Engineering Mathematics and Biotechnology. The biotechnology section is divided into 10 sections. Each section has theory part as well as questions. The chapters has good number of solved questions.

These questions are based on previous year question pattern.You may have similar type of questions in coming exams as well.The book also contains last eight years’ (2010-2017) solved papers of original online GATE Biotechnology to give the aspirants an insight into the trends of questions asked in GATE Examination.

The book also has practice test set.The logic along with problem make this book an excellent companion for exam.The book has close to 1,000 pages and has good rating as well. You can buy the book from below link in discounted price.

Book 2

This book also covers theory as well as problems.The book has around 1,000 pages. The book is good one. The unique feature of the book is 24*7 support via mobile app and online portal.This feature is missing in first book.It also has solved questions from previous year GATE exams.

There is not much difference between first and second book. You can select the first one or the second one.There is not much difference. You can buy second book from below link with discount. I kept this book at second slot due to price difference.

Book 3

This book is third choice.This is not dedicated GATE book.This book covers competitive exams like CSIR- NET, SET, GATE, JNU, AIIMS, JAM, ICAR, ICMA etc. All thesr exams are basically objective type and basic concepts of life science subjects as mentioned above. This book includes the basic concepts of all the important topics of biotechnology entrance and for Phd entrance.

Also this book contains miscellaneous questions collection for student practice or for revision of basic concepts. This book is helpful for the student of different stream of life science who wants to qualify JNU, CSIR NET or other competitive examination. This book is also helpful for those students who wants a brief notes on different topics of biotechnology for preparation of university examination.
