Geology Exam Review

My sister has filled application form for GATE Exam and has selected Geology and Geophysics subject. She needs old year question paper to review the pattern of questions. So is there anyone who will give link to download old question papers of GATE Exam for Geology and Geophysics subject?

As you want to download old year question papers of GATE Geology and Geophysics Exam, so here I am providing following paper:
