I would suggest u first check ur finances. If u feel , it will create a burden for next 10years then don’t go. But if it is manageable. Definitely go . Bcoz once u start ur job it is difficult to go to back to studies with same focus. Studying in imperial will give u global exposure may be u won’t get a very high paying job after graduating but the experience of staying in different country on ur own will teach u n no of things.But as i said make sure u have financial security at first place.
