Expert's reply on one old thread - Will help you also.

Info on CII charges -
Course Books (per subject including examination fee) - 70 GBP
Postage and Packing of textbooks per subject - 14 GBP
Annual Membership fees (designation fees) - 30 GBP

The above is only as per the tie-up between III and CII UK.

So if you are taking 3 subjects in one go then (70+14)*3 + 30 = 282 GBP

1 GBP = Rs 76 (approx) for correct rate please check with your bank.
