Hi Vasudevan,
15 days back i have bought the soft SCBCD. I found it is very good but at this time i can't tell how far it is useful bec i have not taken my exam yet

, planning to take on Tuesday.
And the cost is very less, for me one of my friend subscribed as gift.
But i am sure, it is very easy to buy the product, here is the link. After paying through the credit card it will take 2 or 3 days.
SoftSCBCD Thanks,
