Reattempt

You are asking others question you should be asking yourself.

If you are finding it difficult to study all the papers at one go for the next exam study, one group at a time.

Focus on your studies, make your own notes, use Institute's study resources - latest Study Material, Practice Manuals, RTPs, Suggested Answers, Supplementary Study Notes, Compilations.

Best of luck

I don't think skipping nov attempt is a good choice. As you recently given first group i ty think you are well prepared in first group atleast. As you said you already started reading second group it means you finished some portion of second group also. Now you have three months. Plan your studies in this time frame based on your current position. If after a month or so if you finds it difficult to go for both groups then attempt one as per your choice. Give more weightage to institute's material, prepare short notes of every subject you study. All the best...

is it good to prepare short notes for each chapter in cafinal
