Students of PE-II can enroll for the IT training anytime either before or after the exam.
All you have to do is get yourself registered for the course at any of the branch office of ICAI or authosized centres and pay the requisite fees.
List of such centres is attached herewith. You can contact them for further details.
Also it is advisable to complete the training as soon as you can, as this is the last attempt for PE-II and after this students have to get converted into IPCC, which requires completion of IT training before you can appear for exams.
Best wishes for the Result.
