Since you mistakenly selected Hindi as your study medium in the CUET application but took the exam in English, it's understandable to be concerned. However, this mistake should not significantly impact your ability to study in English at the college level.

Universities generally offer courses in both English and Hindi mediums, especially for popular programs like BA Hons in History. When you apply for admission, you will likely have the opportunity to choose your preferred medium of instruction for your course. Since you've taken the CUET exam in English, you should be eligible to enroll in English medium classes without difficulty.

It's advisable to clarify this issue during the admission process by contacting the university or college where you're applying. Inform them of the mistake in your application and confirm that you want to pursue your studies in English. This proactive approach should ensure that you don't face any challenges in securing a seat in the English medium for your chosen course.
