SUGGEST: Training Center for SCJP ?

Friends,

I personally know Java, JSP etc. but I learn them myself by reading books.
But, the knowledge is not solid enough.

Now, I want to do SCJP.

Can someone pls suggest me a good training center for SCJP in Kolkata.
Without a training center, it will not force me to study hard

Please suggest me a center......
Also, do mention the aprox Course fee.
