First thing is that you have already a great experience and a good degree in hotel management and tourism, I suggest you to that build your career in your field because now a days hotel management and tourism getting slowdown due to pandemic but it is a very broad field in itself. If you want to change your specialisation and want to MBA in finance so you can try because it is also a broad field but your specializations and finance is other things. I hope you get your desired answer.

As far as I know that these are the National University of Singapore (NUS) and the Nanyang Technological University (NTU) are the two topmost colleges in Singapore.

See on the website its specified that a person will be eligible for admission only if the candidate secures at least 90% marks in all his board subjects (of course excluding Hindi in your case), so maybe your physics marks mess up your chances of getting admitted in that particular college.
Best of luck.
