B.Sc

If you have applied for both BBA and B.Sc Economics programs and there is a common entrance exam (SET), then your admission will be based on your performance in the SET exam.
After the SET exam, the participating colleges will release their cutoff scores for each program. If you have scored above the cutoff score for a particular program, you will be eligible for admission to that program.
It is possible that you may be eligible for admission to both the BBA and B.Sc Economics programs if you have scored above the cutoff scores for both the programs. However, you will have to choose which program you want to take admission in, based on your preference and the availability of seats.

Eligibility for admission to TY B.Sc. IT (Third Year Bachelor of Science in Information Technology) may vary depending on the specific requirements of the college or university you are applying to. However, having 1 KT (Keep Term) in semester 2 and 1 KT in semester 4 may affect your eligibility for admission to TY B.Sc. IT. In general, to be eligible for admission to TY B.Sc. IT, most colleges and universities require candidates to have completed the first and second years of B.Sc. IT with no pending KTs or backlogs. Therefore, having two KTs (one each in semester 2 and 4) may pose a problem in terms of meeting the eligibility criteria.

Yes, It is possible to change colleges for B.Sc. Computer Science in the second year if you have backlogs in the first year, but it depends on several factors. Here are some points to consider:
1) Transfer policy: Check with your current college and the prospective college to SEE if they have a transfer policy in place. Some colleges may allow students to transfer, but only under certain conditions.
2) Backlog clearance: Before transferring to another college, you may need to clear your backlogs from the first year. Make sure you are aware of the backlog clearance procedures at your current college and the prospective college.
3) Admission requirements: The admission requirements for B.Sc. Computer Science in the second year may differ from those for the first year. Check with the prospective college to ensure that you meet their admission requirements for the second year.
4) Availability of seats: The availability of seats in B.Sc. Computer Science for the second year may be limited, so it's important to check with the prospective college to SEE if they have any open seats. Changing colleges for B.Sc. Computer Science in the second year is possible, but it requires careful planning and consideration of various factors.
