Thanks a lot, you just solved my problem

Btw, I done B.E(Electronics) so not much aware of GSM architecture, now what to do about GSM in just few days

One of my senior told me to prepare Fiber optics, Microprocessor & Micro-controller along with Communication.
What's your opinion about Micro-controllers & processors??? Please let me know exactly.
Also about math questions, is that come from F.SC+B.E or just B.E???

Looking Forward to hear from you,
Thanks,
Engr.Maryam
