Come back for CA IPCC

Since you're asking now about planning, i presume that you haven't filled the exam forms for Nov-2020 exams.

Well, Nov-2020 exam is the last attempt for IPCC course.
(unless the term gets cancelled due to Covid-19, which is unlikely)

To continue further, you have to convert your reg. into new Intermediate course.

You'll get all the credits of the portion completed earlier (i.e. your articleship etc.)

Everything happens now via ICAI's SSP portal. Nothing from the offices.

So, first get the formalities completed and then proceed further.
