wellllllllll
i have horrible study habits...well not really, i just procrastinate (but in terms of putting the finishing touches on stuff...i already have an idea/grasp of he info...i assess b4 i procrastinate...yeah i know

)
anyway but when i do study
1) i can't study in my apt so i go to the library, student center/union or learning center so i can be in an atmosphere that is conducive to studying
2) my friends and i used to study together in the lounges or make trips to the library together (different subjects but a supportive atmosphere)
3) i used to go into an empty classroom and read over my notes or study in before, in between or after class
4) i tried to set up study groups so we would meet weekly or every 2 weeks to go over what happened in class (i made sure i did my work cuz i didn't want to look like a slacker)
5) put aside either 3-4 hours a day you are gonna go to the library and study...man i would go in the library and it would be son outside and leave at like 3am...tired as hell BUT VERY VERY accomplished
6) if you are anything like me and get distracted easy...BRING YOUR BOOKS WITH YOU when you plan to go to the library...don't stop back to your room first cuz you'll never make it out
7) i actually set alarms in my phone telling me to study
8) i made a reward system for myself...if i successfully did some studying or an assignment i would treat myself to something recreational/ social/ lazy/trip or buy myself something
I hope these help
