dont worry buddy........ upto 3 attempts ur exemption will not go..... and further it will be counted as 63 only..... its only wen u miss out on all the three subsequent attempts ur exemption will be revoked........ trust me i had exemption in Nov 08 exams n i had inquired in the institute..... as regards confusion of old course n new course....... n switching over.... better consult the institute but for sure ur exemption will stay with u till ur next 3 attempts...... all the best n have a rocking career.....
