In general, it is taken as one language and other 3 with the highest marks. But, these three should be subjects with more than 60 percent marks in theory. As far as I know in physical Science courses PCM is also taken into consideration.

After Intermediate, you can go for BCA and after the completion of BCA course you are eligible to take admission to MBA course.
BCA+MBA is a good option as it gives you the technical skills as well as the management skills.
Good Luck.

Yes, definitely you are not eligible for economics hons, as it requires math as a subject in class 12th. Now, if you wish to study economics, then either you can go for BA Programme and take economics, as a subject or go for any hons course and take economics, as your Generic elective. If you take it as your GE for all four semester then you might get a minor in economics.

You will have many opportunities in this branch and the placements are very good for this branch. So work well and achieve the best.

Hi,
There are some courses offered by pu in which entrance is compulsory but in some courses admission is through the class 12th marks, so you can apply for this course without entrance exam. Good luck.
