BCA

Punjab University doesn't have BCA course of its own, you can get admission to colleges which are affiliated with PU such as SD college, DAV College etc. which have BCA course. Secondly, the requirements for BCA for these colleges are bit different , but here is the requirements of SD college. Other colleges will have somehow the same criteria. As mentioned below mathematics should be there in your matriculation. Student having maths and computer science in their 12th do have privilege.
i) 10 +2 in any discipline with at least 50% marks and passed Mathematics as one of the subject at Matric level or ii) Any other examination with 50 % marks, recognized by the Syndicate as equivalent to
iii) 10 % weightage each subject who has done +2 with Math, Stat, Computer Science, computer Application, Information Technology.
iv) 20% weightage in total to those students who studied (Mathematics/statistics) & (Computer Science, Computer Application, Information Technology or Information system) at +2 level be given.

I would suggest you to choose Asian School of Business as ASB has identified itself as a brand, and is among the best colleges for BCA. The institute is UGC approved, NAAC accredited and affiliated to CCS University. BCA students receive 6 additional diplomas/certifications which are in collaboration with the, Career Launcher, NIIT, AAFT, etc. , whereas BCA International includes a ten-day fully paid international residential workshop and certification from the University of Southern California u2013 School of Cinematic Arts, Los Angeles, USA. The institute has its placement cell with 200+ companies connect providing 100% placement and internship assistance (national and international). The placement cell organises numerous activities like pre-placement talks, on-campus interviewing, events such as placements weeks & placement workshops to increase the employability skill of students. The college has qualified and experience faculty, excellent infrastructure, provides good exposure and opportunities and the level of discipline and studies is also good. IPU colleges aren't bad either but in comparison with ASB one should definitely prefer the latter. Hope this helps you. Feel free to ask any question.
