Minimum attendance for itt

I want to register myself for ITT training.

But the timings of my ITT are clashing with my IPC Exams.

So, I want to take 9 days off out of 31 days training.

Will there be any problem like minimum attendance ?

As per ICAI rules 90% i.e. 26-27 days attendance is mandatory. Do they really follow this policy ?

Should I register for this Batch or not ?
