Firstly , If you're going for just one group...go for Padhuka instead of V.K Agrawal as it covers comprehensively the whole syllabus + past examination questions + past RTP questions which can be a great advantage. Also do Professional Ethics from V.K Agrawal as it is explained nicely in a lucid language there with almost all of the past examination questions.
Secondly AAS's are no longer applicable...they have been replaced by SA's. Their content more or less remains the same ....just their names have been changed. Do the SA's from V.K Agrawal as it is given in a brief and simple language there which is more than sufficient from exam point of view.
Thirdly , IFRS is only applicable for C.A Final New Course....so if you're in the old course...it's not applicable to you.
And lastly it is always the best idea to prepare first group from compilations especially MAFA and Accounts which is more than sufficient to clear the exams with flying colors.
And most importantly for MAFA and ACCOUNTS.....don't miss the ICAI MODULE QUESTIONS....as questions have been copy pasted from the MODULE in the past few examinations.
