tldr: sat is fking easy and better than ACT. It has a clean and crisp structure with a nice majority of easy questions across the sections.
Like Jaysea214 has explained, the SAT test format has been largely altered to become a standardised score out of 1600 instead of 2400 (Please check out the collegeboard website for the logistics of this). Having practiced rather lightly for the old and new sat using free material online, I sat the exam in June. And believe me, if you are a capable student, you only need to study intensively for the reading comprehension section which as passages about the constituition. Boring stuff tbh if you ask me. Anyway, maths is a breeze if your maths level is > general maths. It is very easy to score 35+/40 on maths with little to no prep on both the maths section (Calculator and non calc) . There is also the essay which I kinda messed up because this sat exam was kinda a learning experience. I didnt go in with declarations of attending the ivy 10 universities. More so, I remained really fking calm which helped
Got 1390 as my final score which is decent enough for international study. (Dont freak out, this score is scaled and really very much within your capability). The cut off for Berkeley was 1410 :'( the feels, oh well. Like I would go anyway.
CHEERS and GOOD LUCK BRO
TBH: Sat is heaps better than ACT. Its more popular and less specialised. ACT if I'm right, needs legit prep for chem, phys etc. SAT is so general and chill with so many breaks, I forgot this was a 'high stakes exam' for american kids.
