Hi Bk Kumbhkar,

There are many posts in SSC like, clerks, official post, MTS and GD. SSC exam are for both students who is 12th pass and graduated. For 12th basis SSC CHSL exam held, and for graduated student SSC CGL exam held. Level of exam is same as Bank exams, and a good preparation is needed to crack this.

There are two papers in SSC, preliminary and main. Once you clear preliminary exam then you are allowed to give main exam. Once you clear the both then you will have final interview round. 

There are many coaching for SSC in everywhere. I don't know your location. But, coaching does nothing when you won't give time to yourself. 

You should have to study self for this.

Good Luck!
