  1. I have completed my Second year. (INSTRUMENTATION ENGINEERING) looking ahead for Gate preparation . Can u plz suggest me which books to buy..and how to start preparing for Gate ..

  2. I am 3rd year instrumentation engineering student. Can I purchase the study material or books suggested this year only since I will be taking my gate exams in 2017 or do the books/ study material change every year

    • Hello Sanjay,

      If you are going to start your preparation for GATE from this year then you have to purchase study material and books this year.
      Because competition in GATE exam increasing year by year and will increase continuously. So it would be a wise decision to start your GATE preparation as soon as possible.
      GATE syllabus doesn’t change frequently so you can buy material and books any time.

      For important subjects and topics buy a previous years papers book in which you will find all the analysis very well including GATE 2015 paper.
      GATE 2016 Reference Books : http://www.gate2016.info/gate-2016-books/

      First you have to have a book of previous GATE 20-30 years papers with solution so that you can get a good idea about GATE questions.
      Then atleast one standard book of each subject. All books required for GATE exam preparation in Engineering are mentioned in above link.

      Feel free to ask if you need any help in future & join us @ Google+ / Facebook for getting regular updates.
