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 iit jam u should atleast know about all 32 classes, normal class of every crystal system and forms of that normal class. In jam papers u will find many questions from this part. Questions asked from this topic are either mcq or Nat..... And also remember HM symbols of these crystal classes
I am just going through it..aand I will ask you people..PLEASE tell how to remmeber or understand some logic of the descriptive name of the 32 point groups..like 4/m2/m2/m == DITETRAGONAL DIPYRAMIDAL CLASS. I am confused how to remember the descriptive names of ecah classes ..Although I know each point group is uniquely identified by its HM notation ,not by its name......But Qs are asked in JAM regarding this descriptive names..I will show you later.
If u are facing problem to remember these names then u can do what i did during my preparation.... Go to youtube and search for \u092D\u0942 gyaanam channel... Here u will find lectures which will help u, these lectures are delivered by my senior Piyush Srivastava who secured Air 1 in iit jam 2016 . I m attaching a link here please go through it ......https://youtu.be/3jW1BiSyNTU
