Is this happens in Main SAT also. i got 18/22 correct in maths but what the hell is this, how is this incorrect.

Can anyone help me to solve with regression and like how should we approach such types with the help of desmos

hey guys, my sat test is tomorrow, and i am still not confident about reading section. Any tips

I’ve been grinding math a lot but not that much on English I jus did a dull practice on English and I think maybe if I grind out my weakest link standard English rules I can make reach 600 I want a 1200+ score

I got the answer right because I've seen the question before. But I still don't get how to solve this question. Like the whole smallest possible mean of A and largest possible mean of B (the POSSIBLE mean and all makes it confusing)
