hello aspirant,

you can choose either of the course, but if it comes to choosing the best one then among Bachelor of Commerce (B.Com) and BBA , BBA can lead to MBA, B.Com is better as it can lead to a wide array of Post Graduate specialisations like MBA, M.Com etc. ... Thus, it makes much more sense for the students to do a B.Com degree along with CS and Banking & Finance course

hope that helps
