GATE Biotechnology

 
The GATE examination consists of a single paper of 3 hours duration, which contains 65 questions carrying a maximum of 100 marks. The question paper will consist of only multiple choice objective questions. Each question will have four choices for the answer. There will be negative marking for each wrong answer, as explained in Question Paper Pattern.
 
 
ELIGIBILITY
The following categories of candidates are eligible to appear for GATE:
 
a. Bachelors degree holders in Engineering/Technology/Architecture (4 years after 10+2) and those who are in the final or pre-final year of such programmes.
 
b. Masters degree holders in any branch of Science/Mathematics/Statistics/Computer Applications or equivalent and those who are in the final or pre-final year of such programmes.
 
c. Candidates in the second or higher year of the Four-year Integrated Masters degree programme (Post- B.Sc.) in Engineering/Technology or in the third or higher year of Five-year Integrated Masters degree programme and Dual Degree programme in Engineering/Technology.
 
d. Candidates with qualifications obtained through examinations conducted by professional societies recognized by UPSC/AICTE (e.g. AMIE by IE(I), AMICE(I) by the Institute of Civil Engineers (India)- ICE(I)) as equivalent to B.E./B.Tech. Those who have completed section A or equivalent of such professional courses are also eligible.
 
e. The students of Integrated Master Degree and Dual Degree programmes in Engineering/ Technology are eligible to appear in GATE 2010 in order to qualify for the postgraduate scholarships in their own institutions only. They are not eligible for admission to a fresh M.E./M.Tech. programmes.
 
 
GATE BIOTECHNOLOGY (BT) paper consists of basically 3 sections:
  • Mathematics
  • Biotechnology
  • General Aptitude
(All three are compulsory)
 
Pattern of Question Papers (Biotechnology)
There will be a total of 65 questions carrying 100 marks.
 
Q.1 to Q.25 (25 questions) will carry one mark each (sub-total 25 marks). Q.26 to Q.55 (30 questions) will carry two marks each (sub-total 60 marks). Questions Q.56 - Q.65 belong to General Aptitude (GA). Questions Q.56 - Q.60 will carry 1 mark each (sub-total 5 marks) and questions Q.61 - Q.65 will carry 2-marks each (sub-total 10 marks).

Q.48 - Q.51 (2 pairs) are common data questions and question pairs (Q.52, Q.53) and (Q.54, Q.55) are linked answer questions. The answer to the second question of the linked answer questions depends on the answer to the first question of the pair. If the first question in the linked pair is wrongly answered or is un-attempted, then the answer to the second question in the pair will not be evaluated.
 
NEGETIVE MARKING
For Q.1 - Q.25 and Q.56 - Q.60, 1/3 mark will be deducted for each wrong answer. For Q.26 - Q.51 and Q.61 - Q.65, 1/2 mark will be deducted for each wrong answer. The question pairs (Q.52, Q.53), and (Q.54, Q.55) are questions with linked answers. There will be negative marks only for wrong answer to the first question of the linked answer question pair i.e. for Q.52 and Q.54, 2/3mark will be deducted for each wrong answer. There is no negative marking for Q.53 and Q.55.
 
(GATE Biotechnology paper will also contain questions on Engineering Mathematics carrying 15 marks)
