I say information technology or Computer Science. Very in demand and if we look at the world now, we are in the digital era and they are the ones needed the most. Engineering as well is profitable and always in demand wherever you are. Obviously you should pick a program where you excel at and you will be happy at but a factor of choosing a degree to study is how rich it can make you. I guess I am talking about the degrees with biggest ROIs these days.
What else are profitable programs?
Sure IT, CS, ComEng are the best and in-demand jobs and course today, but you should know that there are lots of people who are in that industry already thus it make its congested already and it need a lot of skills before you land to some descent job and company.
Next is Finance, the Accounting or Accountancy, either WFH setup or office based can be applied same on IT, then Aviation, well this one needs more money to learn in any kind of Aviation schools. But I got a hint from someone in socmed, that joining in Air Force then continue to school Aviation can help a lot with financial needs, it just need time as
you as you needit take time in Air Force and some requirements like height, training, etc.
before it happened.
