Some students prefer studying alone but others prefer studying in groups. This have got advantages and disadvantages, personally I prefer studying alone.

I prefer studying alone because you can study better like this, with yourself, thinking in the problems you have and resolve its alone, this is the best form because you can learn more if you see you errors and correct its for yourselfs. The disadvantages it has got are it can be more dificult than studying with your partners, because the doubts you've got.

The advantages of studying in groups are you have got more help than if you study alone, and the disadvantage is you have got more distraccions, because if you study with your partners you will possibly distracted.

the best option in my opinion is you often study alone and sometimes go to study in groups to resolves your doubts.
