Here's my problem. I'm a high-school student, from Africa, I will now have completed my last year there; However, the only choice available to me, in my country, are either engineering schools or medical schools. But my interests lie elsewhere, since I want to become a theoretical physicist, and that's obviously not possible with these two options. I've looked at foreign programs, in particular, undergraduate programs. I know beforehand that getting full scholarships is extremely difficult, but I thought that it would be a good idea to at least try. According to my limited knowledge on the exact procedures that are a necessity to get into a foreign university (either the US, or the UK, I didn't look yet at other possibilities), but one should make an application before applying for a scholarship. And to do so, one has to fit certain requirements, amongst whom are a set of standarized tests, the SAT/A Levels. I've spent nearly 5 months, going to the British and US councils, asking many institutions, but none offered the possibility to take either of these tests.
I now have exactly zero idea on how to proceed, which kind of gets depressing, and I'm worried that with the advance of my age, I may not reach my goal.
(Sorry in advance if this question possibly violates Academia.SE policies, but in case it gets closed, I ask the interested persons who want to provide some help [even an infenitesimal one] to send me an email which you can find in my profile)
