GATE 2017 Test Series

Graduate Aptitude Test in Engineering (GATE) is one of the toughest and most competitive entrance exam in India to seek admissions in masters courses at top Engineering Universities like IITs & NITs and jobs in various PSUs. In GATE 2016, over 1.5 lakh students appeared for the exam for Computer Science and IT (CS) stream. There were approximately 450 seat in IITs for M.Tech and other post-graduation courses in Computer Science and IT. Qualifying marks for CS was 25 (General), 22.5 (OBC) and 16.67 (SC/ST) in year 2015. We, at Examinia, are well aware of intense competition that GATE entails. We strive to provide the most comprehensive practice material with top quality content for GATE CS. Plan your preparation for GATE 2017 with Examinia.


The Graduate Aptitude Test in Engineering (GATE) is mandatory for pursuing M.Tech, MS in prestigious institutes viz. Indian Institute of Science (IISc Bangalore), Indian Institute of Technology (IIT Bombay, IIT Delhi, IIT Guwahati, IIT Kanpur, IIT Kharagpur, IIT Madras and IIT Roorkee),National Institute of Technology and other universities and is jointly administered by The Indian Institute of Science (IISC) and seven Indian Institute of Technology. GATE 2015 score is valid for THREE YEARS from the date of announcement of the results.


The examination for all the papers ( AE, AG, AR, BT, CE, CH, CS,CY, EC,EE,EY, GG, IN,MA, ME,MN, MT, PH, PI, TF, XE and XL) will be carried out in an ONLINE Computer Based Test (CBT) mode where the candidates will be shown the questions in a random sequence on a computer screen. In the papers bearing the codes AE, AG, BT, CE, CH, CS, EC, EE, IN, ME, MN, MT, PI, TF and XE, the Engineering Mathematics will carry around 13% of the total marks, the General Aptitude section will carry 15% of the total marks and the remaining percentage of the total marks is devoted to the subject of the paper. In the papers bearing the codes AR, CY, EY, GG, MA, PH and XL, the General Aptitude section will carry 15% of the total marks and the remaining 85% of the total marks is devoted to the subject of the paper.

Multiple Choice Questions (MCQ)These questions are objective in nature, and each will have a choice of four answers, out of which the candidate has to mark the correct answer(s).Carry 1 or 2 marks each. One third of mark(s) will be deducted for wrong answer.
Numerical Answer QuestionsFor these questions the answer is a real number, to be entered by the candidate using the virtual keypad. No choices will be shown for this type of questions.Carry 1 or 2 marks each. No negative marks will be awarded for a wrong answer.
