Dear Nidhi, It is always better to move rather then to stop. If you can assure yourself that you will clear both groups in may then dont give this attempt but in CA this assurance is not possible so it is advised to give attempt with 1 group.

Its better to give 2nd group because you get more time to study. Further 1st groups have 2 subjects which are more conceptual and may take time to understand. and the most important this time there is long break for Direct Tax which will help you to prepare well.
