Regarding CA final exam form

I have cleared Ipcc in nov 2016 attempt. I have applied for  Final registration on 7/02/2017 but had recd registration letter from institute untill now, But in online reprint letter servies ofr institute letter i am able to see my registration letter and on this basis i filled my exam form by putting the same date in the regitration date column in exam form. The exam form pdf shows my photo and signiture. Am i still required to sent the exam form to institute??
