ONE TIME CA, ICWA,DEGREE IN DISTANCE

You have to submit form 112 in case you want to do other course while pursuing CA.

Futher you can do only one course with CA whether regular or distance it does not matter at all only one course.

I hope your doubt has been solved.

112 is basically needed when u do other course with CA articleship going to certify that the timings are not clashing... u can do any no. of course as far as it is distance learning.
