hello anons, brainlet here. I genuinely need help all memes aside.

I live i na shit country with bad schools and im 18. Im lloking to move away and take a mechanical engineering univeristy.

However, i know very little about anything that is not arithmetics, and i have a foggy mind and low attention span.

Any suggestion you guys could give i would treasure. Anything i can do or learn to make my life with maths easier and to be a more focused person.

Thanks in advance.
