  1. Hello SURENDRAN,
    There is a book in market QUESTION BANK IN AGRICULTURAL ENGINEERING BY ER, AMANDEEP GODARA. The book also contains answers with explanation of last 9 yrs GATE. If u read this book only, you may get a good position in IITs.

  2. Hello Sir/Madam,
    This is Surendran.K, can you please tell me where can I get the solutions (and not just answers) to of GATE-2013,14,15 of Agricultural Engineering stream.Thank you so much for spending your precious time to read my request.
