If you have chosen only the three domain subjects bio chemistry and physics in the CUET exam and forgot to select a language subject then you must know this you may face problem getting into most universities for BSc courses that require one language paper. Some courses like BSc Agriculture or BSc Life Sciences in certain universities may allow admission with just domain subjects and no language, but many central and state universities including ones like Delhi University require at least one language test to meet eligibility . In your case without a language score you may not be able to get admission in BSc honours programs in most top universities. You could still aim for courses in private or newer universities that do not strictly require a language paper. It is always best to check the subject mapping and eligibility criteria of each university you wish to apply in.

If a correction window is open before the exam or result, you can add a language subject and improve your eligibility. For now you should review the eligibility of each college carefully and consider retaking or adding a language test if needed.

If you have taken only the three main domain subjects bio chemistry and physics in CUET then you will appear in those tests only and your score will be based on those papers. CUET requires you to choose domain subjects that match your intended course after 12th and you can also add language and general test papers for better rank. Since you selected bio chemistry and physics you are prepared for science and medical related courses through CUET. After test completion your score from these papers will be normalised and used to calculate rank. You can use your CUET score along with 12th marks to apply for admission in university science courses like BSc Life Sciences, Pharmacy or allied health streams.
