What exams might I need to take for admission to UK universities given my bachelor's degree and gap years?

You will typically need to take the IELTS (International English Language Testing System) to prove your English language proficiency for UK master's admissions. Most UK universities require this, but some may offer an IELTS waiver if your bachelor's degree was taught entirely in English - this depends on each university’s policy.

Additional standardized tests like GRE or GMAT are usually not required unless you apply for specialized programs. Your gap years are not a concern for most universities, as long as your academic record and work experience are strong and explained in your Statement of Purpose.
