hey time is the issue with many of the students not just you who do regular articleship. so try n manage ur time some how. make a list of things that u should do and things u should not do. Prioritise things in ur case articleship with studies and try to strike a balance between the two.
Don't worry about whethet B.Com is sufficient or not with C.A.. Do ur graduation B.Com(P) with C.A with devotion and forget about any other course as of now due to ur time constraint. Focus on ur PCC now and try n balance it with work.PCC is very important 4 u now. Focus on PCC.
Do proper time management. That's the essence of our profession.
ALL THE BEST
