Permission for other course

I don't think/ recall there was any notification that exempts from taking permission. Though one could do one graduation course along with articleship, that too when timings didn't clash with articleship timing.

The announcement I could find and recall is here:

Form 112 to seek permission, had to be sent anyhow. If you mean condonation of breach for the relevant regulations, this maybe what you are talking about:

You get delayed membership for non-compliance.
