How can I get an online or telephonic gudiance session from Shiksha experts?

I am a 12th comm. stud. and i was looking for career options avail. for me along with respec. colleges. Also found out that i have interest in biology so, is there any possibility for comm. stud. to study bio somehow because i read about the new rules by AICTE which allows comm.stud. to take btech.
