On Question asked by student community
Hello,
Choosing CSBS engineering at Techno Main Salt Lake for the 2026 session can be a good option. The CSBS course focuses on both computer science and business skills, which helps students become job-ready for roles in technology, analytics, and management-related fields.
The placement performance for this branch is generally good. Students usually receive offers from software companies, IT services, product-based companies, and analytics firms. The usual salary range is around four to six lakh per year, and higher packages are possible for skilled students.
The academic fee for the CSBS program, excluding hostel charges, is typically between three to four lakh for the full four-year course, though it may change slightly depending on the year.
If you are unsure about your entrance exam rank, you may still get admission depending on counselling rounds and seat availability. If you are interested in computers, programming, logical thinking, and learning business-related subjects along with technology, CSBS can be a suitable and practical choice for your future.
Hope this helps you.

Hello,
If you mistakenly registered as a General category candidate for JEE Mains 2026, but you actually belong to OBC-NCL, you cannot change the category unless the correction window specifically allows category correction. The National Testing Agency (NTA) sometimes provides the option to edit category during the correction window, but this is not guaranteed every year.
If category correction is allowed, you can upload your valid OBC-NCL certificate and update your category. If the correction window does not allow changing the category, then you will have to appear as a General category candidate for that attempt and will not be able to claim OBC-NCL reservation benefits for that session.
Make sure to keep checking the official correction notice to see which fields can be edited.
Hope this helps you.
Hello,
If you mistakenly entered your serial number instead of your admission number during JEE Mains registration, you do not need to worry. NTA mainly verifies your identity through your name, date of birth, school details, photographs, and other documents. The admission number is not used for eligibility verification, so this mistake usually does not cause any issue.
If the correction window opens and allows editing of personal details, you can correct it. If the field is non-editable, you can leave it as it is because it will not affect your exam, admit card, or result. Just make sure all other details are correct.
Hope this helps you.
