/sci/ - Science & Math

I gotta study for europoorean country math exams for next year, what in the FUCK do I study? I feel overwhelmed looking at Khanacademy, do I look by grade or by subjects? I saw that it has a SAT study guide but I assume the SAT is less demanding cuz burgers lol + paid

for reference, I struggle with even basic operations like multiplaying fractions.
im a total retard around geometry. I somewhat understand statistics and linear/quadratic/cubic functions, but linear algebra and equations always confused me

so what pill you recommend to me bros? can I make it with ~2h of study time each day?
