CBSE 12th

Hi Aditya,
According to the rule, a student must not take admission in any college if he/she plans to appear in the improvement exam of CBSE. A form has to be signed by a principal stating that the candidate appearing in the improvement exam has not taken admission in any college.

The admission in DU is on the basis of class 12th percentage. For B.A. (hons) English, best 4 subjects marks are calculated against the cut off released by DU. If you add physical education in best 4 subjects, your some marks are deducted. You can also download the brochure of Delhi University, and you can also check out the last year cut off for different course on Delhi university website.

For PCM students, there are many choices in computer stream. So, you go in IT, B.Tech IIT hardware, software, etc. Good luck.

You can go for Bachelor of Arts, as it allows you to opt from a number of subjects. You can opt any subject of your choice.

If you think you can perform better, it is a good option. But, it depends on what course you are willing to opt.

58% is very less. Better you prefer to re appear for the class 12th, and get admission for your course.

I think you can do BA Maths hons., but not B.Sc. Maths, because that course is for Science stream student.
