Is it possible to study in the UK without IELTS or PTE if I have good English marks in 12th grade?

Yes, some UK universities accept strong 12th-grade English marks from Indian boards (like CBSE or CISCE) instead of IELTS or PTE. Typically, you need at least 70% - 80% in English, but the exact requirement depends on the university and program.

Some universities may also ask for a Medium of Instruction (MOI) letter confirming your education was in English.

However, this policy varies, and UK student visa rules often still require formal proof of English proficiency, which may mean taking IELTS or an equivalent test.
