Training In Design Software, CAD near Coimbatore

I am studying final year mechanical engineering. I have plan to do M.S through GRE. For that exam they need me to do any research related to my studies . I have interest in (CAD) design software. I have learnt basics and can access the software on my own. Can you give me any suggestions about the CAD software I can learn and gain some knowledge? I know basic things about pro-e, catia, unigarphics, ansys... I can create any type of part diagram in that. Looking for suggestions on coaching, training centers near Coimbatore.
