Hi, I'm in CS Professional level and had done my B.Com from Shyamlal College, University of Delhi. It is always preferred that you do your CS and B.Com simultaneously. If you're not able to get into North or South Campus, get yourself registered in DU SOL and focus more on CS as it is a Professional course and levels after foundation (i.e. Executive and Professional levels) are tough and competitive.

Government Victoria College, Palakkad is one of them.

As per your said score, you cannot get admission in DU but you may get admission in a non-reputed college of Delhi University.

You can definitely wait, but you may never know that there will be seats left after the first cut off or not, so keep that in mind. Mostly, for the best courses in DU, the seats get full in the first cut off only so they don't release a second cut off for that course. If you are getting admission in the first cut off, but you don't take it right now, you won't be able to get it later.

B.Com (Hons) is a more detailed analysis of the topics whereas B.Com is a bit simpler as compared to B.Com (Hons) as there is not much detailing and the subjects are easier. If you have high marks in 12th you can take up hons but maths as a subject until 12th is compulsory for honors otherwise you can take simple B.Com.
