Can I do B.Tech via CUET? Which colleges are taking admission via CUET?

With a CUET normalized score of 218, admission to microbiology or biotechnology in reputed DU colleges is unlikely for the general category. Programs in microbiology and biotechnology would typically require scores of at least 450 to 500 particularly in colleges such as Gargi, Ram Lal Anand, or Bhaskaracharya. In the case of a reserved category admission, it may be considered in subsequent rounds or colleges that are of lower demand. Watching the CSAS portal for cut offs and vacant seat rounds may be helpful. Aside from considering options related to 'life sciences' (not sure if there is anything available or cheap enough if on a budget), you could also look for backups at other universities.

Yes, you can get a BBA seat at IPU through CUET if all the IPU CET counselling seats are filled and there is still availability. Register for CUET and choose the subjects English, Business Studies, and General Test. After the results are published, check IPU's spot counselling notifications. If you have a valid CUET score then apply on IPU's admission portal, upload the documents required, and pay the admission fees. The admissions will be based on merit and available seats. You must have passed your class 12th with a minimum of 50% marks with English as a subject. Keep checking for updates from IPU so you can be prepared for document verification and in case you are called for counselling. CUET is a useful backup option if the CET seats are already filled.

Given your CUET 2025 score has 651.58 out of a possible 750, your predicted rank can assume all factors fall in a normal range, that your rank is between 3,000 - 6,000 out of over 10 Lacs runners - this is very good and you will be a top 1 - 2% candidate. However, your exact rank will depend on several factors depending on your subject combination, normalization, and how many students selected that subject combination as well. Because CUET does not release a common rank list or merit list for CUET, the universities will use your normalized scores, percentiles - so each university can prepare their own merit list. However, with even your normal score (even if your preferred course you want to do it has reasonable competition) you should have a good chance for at least probably the top central universities!
