any non generic tips on how to focus on studying/maximize time? i have the attention span of a goldfish and my exams are coming up, my brain feels like mush .__.

i started doing art seriously like a year ago after doing it on the side for three years and holy cow have i got a long way to go ... anatomy is still kicking my ass. i really wanna get into learning to draw mecha and steampunk character designs cause they just look so freaking cool?? i suck at drawing complex shit so i wanna work on details and take it from there
