autocorrect will be the death of me… “In fact, IF you say”…
I wouldn’t take the classes on Global Freshman Academy, because if you take the credits, you’ll lose your “freshman status”, ie., never enrolled in a post-high school program. (“pay to pass” yemeni English classes don’t count, fortunately for you). This is important because only freshmen are eligible for scholarships, basically. GFA costs $49 per course, apparently (?)
HOWEVER this is a great idea: take remedial courses in everything, through EdX and Coursera. It’s free, you learn on your own time, and you can get certificates that don’t count against freshman status but show you’ve reached such and such level. The certificates are very cheap and you can get them for the specific science classes you’re missing. You have to take pre algebra, algebra1&2, geometry, trigonometry, precalculus, plus physics, chemistry, and biology - at a minimum.
Australia is more complicated than the US:
on the one hand, it’s very open for immigrants and wants people with agricultural/engineering skills. If you get a degree there, there’s no visa hassle like in the US (mostly because in the US offshoring companies “take” the visas meant for students who graduate from US colleges. This is infuriating because legit international students who qualify for H1B’s individually don’t get them, and American workers are laid off in batches while batches of foreign workers based in other countries get these visas which weren’t meant for them. There’s an article in the NYT today about this, which forgets to specify that H1Bs are NOT meant for this purpose :(. The immediate reaction to the article is “lt’s cut those H1Bs”, when the reaction should be “let’s stop the loopholes that allow the abuse of H1Bs”. The result is that, if you have a skill that’s in-demand and have a job offer, you can’t take it because offshoring companies have taken/bought thousands of visas for people who weren’t US-educated, aren’t in the US, don’t have a job yet… and so everyone loses. Because of these offshoring companies, getting a visa has become a nightmare for qualified international students who graduated from a US college whereas in Australia, things are very streamlined: get a degree in our country, get a job offer, get the visa, a couple years later you’re a permanent resident. Same thing in Canada.)
BUT getting a degree will be more complicated since they have no scholarships and are incredibly expensive for internationals. So, if you get there and manage to get a degree
Another issue is that no, they won’t admit you based on you credentials - you’re not qualified for technical courses without stem pre-requisites. SO, they’ll recognize your high school diploma and tell you you’re allowed to study history, or English Literature. For agriculture or engineering, you need the pre-requisite stem courses. If Australia really is your goal, then Global Freshman Academy could indeed qualify you for first year admission - email Institutes of Technology and Technology colleges, include the GFA link, and ask whether completing a program through that would indeed “count”.
