I am all confused with the CWA Forms

Here's my situation :

I have passed my CS Professional Programme. Also, B.Com (Hons) completed.

Now I wish to enroll for the CWA Intermediate course under Simplified Postal Coaching. So I got the Prospectus, and I am all confused with the huge number of forms present in the prospectus. The forms present in the Prospectus are :

Identification Form (For foundation course)

Form of Application for Registration (Form I) as A Student

Registration for Practical Training (Form T2)

Student Information Form

Form of Application for Enrollment For Foundation Postal Tution

Postal Coaching Form (Form I)

Application form for Obtaining Exemption(S)

Application form for Remitting Fees to the Institute

Journal Enrollment form (Postal)

Identity Card

So can you scholars please help me out which forms am I required to submit to the Institute?

Another question :

I enquired for the fees to register myself, they told me Rs 8500/- by Draft AND Rs 8200/- by Cash. Why is that so? Further the Registration fees for Postal Coaching is only Rs 7000/-

Thanks.
