In a big dilema ,plz giv me suggestion

I agree with all the suggestions that you get your degree first and work only AFTER passing.

The whole myth of "Practical Exposure" has been inflated by CAs to get willing "free labour" for their firms.

In the end, neither the Institute, nor any CA will care whether you pass CA or whether you spend the rest of your life as a glorified clerk. 

Both qualification and working experience are important. I suggest you to join some mid sized firm and simultaneously you concentrate on your studies as well. Finally degree is also important.
