If I opt for two courses, will I get a scholarship for one of them to manage other expenses in UK for a Master's?

UK universities rarely allow pursuing two master's programs at once, and scholarships are usually given for only one course. Securing funding for both is very difficult. Focus on a single master's program and work on meeting its scholarship requirements, including improving your IELTS score if needed. This will give you the best chance to get financial support and successfully pursue your studies.
