What's the different between study hard and study smart ?

Hello. I want to study smart. But I dont really know what's the different between studying hard and studying smart.

And, how to study smart ?

Thanks in advance.

Ummm, study hard is studying like everything about the chapter that you are reading about
and studying smart is you look at the test in advance when your teacher is out of the room and study only the things on there

Haha just kidding. Honestly I really don't know, but this is my opinion. If you study smart, you only study the major points on your notes (not like every single thing, even the little tiny non-important things.)

You can spend a lot of time studying and make it hard or you can make the most out of every minute - stay focused and study smart. Studying with the fervent desire to learn is
to study smart. Just putting in long hours is to study hard.

Study smart...it's all about time management. Also, before a test, get plenty of rest, a good night's sleep and eat healthy. Study in short times periods. Review. Concentrate on what is the most important aspects of the material. Ask the instructor what he/she considers most important. Teachers have very different teaching styles.

I agree wtih etyhvh.. Concentration matters when you study. If you really focus on what you're studying, you won't waste any time so you get the most out of it.. It's studying smart.
Studyin hard is like studying until you got the whole lesson. you have to try hard sometimes even without resting. When you study smart, you've got not stress, just concentrate and rest sometimes.
Lol, thats' just what I think.
The best of luck!
