Hope you are doing well,
For admission into B.Com (//B.Com) Hons, one needs to have 50% at least in their 12th grade. If this criteria is fulfilled, you will be eligible for admission into DAV College Chandigarh. If you have got 84.5%, then you might be eligible for the course. You should apply and check if you get admission or not. As far as the merit list is concerned, you will find it on their website very easily.
Hope this answers your query.
