Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

For notes of mineralogy and crystallography , i would suggest you to go through the books and make short notes for the respective topic. And for notes you can prefer Tulane notes. Mineralogy-- Dexter Perkins and Tulane notes is more than enough.(For various mineral Or silicate groups basically go through the book by DH Zussman) Crystallography-- Dana Optical Mineralogy-- Nesse Or Paul F Kerr. Refer these books and make some short notes for quick recapitulation and it will help you alot in peak time. I'm adding some links so that you can have deeper insight in mineralogy. 1) https://www.google.com/url?sa=t&source=web&rct=j&url=http://ruby.colorado.edu/~smyth/G30101.html&ved=2ahUKEwiA2_G_0rXyAhXUc30KHYjUBgIQFnoECAMQAQ&usg=AOvVaw06ctGbtJUc2jl0RVI_wkZ1&cshid=1629120458107 2) https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.science.smith.edu/geosciences/min_jb/Lecture_Notes.html&ved=2ahUKEwiA2_G_0rXyAhXUc30KHYjUBgIQFnoECCYQAQ&usg=AOvVaw2p-hL4qxFP1b_Y7Ue2yRxs&cshid=1629120555859 3) https://www.google.com/url?sa=t&source=web&rct=j&url=http://users.metu.edu.tr/lunel/&ved=2ahUKEwiA2_G_0rXyAhXUc30KHYjUBgIQFnoECCoQAQ&usg=AOvVaw0zo-6jVdidrn7nTcCID0_h&cshid=1629120626287 Hope it helps:)
