Hello Aspirant, 

To be very honest if you are pursuing for Chatered Accountancy then minimum 6hrs self study each day is important and it would be best if you devote each section 2hours daily.

Now if we talk about similarities between Bcom 1st year and Foundation course syllabus then there are many topics that are covered up in accounts like joont venture,  depreciation and Hifo,lifo methods,etc . In bcom 2nd year Mercentile law will be the common  subjectin both.

Hope this helps you 

Best of luck!
