Hey Sivasia be praticle yaar. instead of preparing both groups you should prepare for group-1 of CA final only because preparation & revison of both group is not possible for because u r doing job & have not suffcient time to study & revise all the 8 subjects. so it is my advice to u to concentarte on group-1 because it is easy as compare to group-2. and follow this method for study :
monday morning : 5 to 8 am Financial reporting
Monday evening : 7pm to 10 pm : SFM
Tuesday : 5 to 8 am Corporate & allied law
Tuesday : 7 pm to 10pm Auidting
then same routine on FR & SFM on wednesday
then same routine of Law & Audit on Thursday
and so on...
and every sunday there should be a revison of all subject that u studied in week. because revison is must before exam.
and dont forget to solve study material questions, Practise manual questions & RTP & Mock test paper of the ICAI for all the 4 subject for Group-1.
and for Law u may refer munish bhandari & for Audit u may refer Surbhi bansal & For SFM & FR u may refer JB Gupta and MP Vijay kumar for FR.
and be punctual in your studies & work hard to acheive your aim of CA.
best of luck & happy reading..
