If your family can afford it, go to LSE. Then try to get a job in London if you are keen on working there.

If not, come back to Singapore and I don't think you would have an issue landing a good job.

If you want to hedge, you can use your spare time to study for ACCA. There's no need to go to NTU Accountancy actually.

IMO, it's better to take a degree in a non-accountancy area and take ACCA if you are keen to have more options.
