Yes can confirm. I mean, it's great if u get to go to a good US school for UG, but it's not necessary. Would definitely recommend going to US for grad school though. If u guys plan on doing that, start looking into taking the GRE tests sometime between now to midway through your UG degree. Every grad school requires GRE tests, regardless of the course. The results are valid for 5yrs, and aren't hard. You'll also need to take the physics subject tests, but you can do that near the end of your degree.
The GRE has 3 parts - analytical reasoning (i.e. essays), verbal reasoning (i.e. comprehension), and quantitative reasoning (i.e. numerical literacy). Numerical literacy will be easy - it's non-calculus based and tests you on basic problem solving, looking at data etc. Analytical reasoning might give you a very general statement, and it asks you to critically justify/opposte it. Comprehension is your general english/reading skills. The first two are straightforward and shouldn't require too much study, but you might might need to spend more time studying for the comprehension though - questions might be like "which of the following 5 words best fits this gap in the sentence". That might sound easy, but they'll give u 5 words where you've never even heard of 3 of them. I found a website that had recommended list of 1500 words to know, and I spent a solid 1-2 months committing that to memory. I've attached it if your interested - see how many of these you know.
You can find sample GREs sections on the website to see what it's like. You can also take each section separately (up to 5 times a year), which is why it might not be a bad idea to take the english sections straight out of HS while your english skills are still fresh (assuming that you're planning to apply for grad school within 5 years). If I could go back, I would've done it sometime in the uni summer holidays just to get it out of the way.
still interesting though
