How to form a study group
Find your group :
A good start is talking to the person sitting next to you. If you don't know them start by introducing yourself and ask how they are finding the class, then you can lead on naturally to asking if they'd like to study with you. Odds are they'll know someone else who want to join in too.
Beware of keeping your group to a good size. For a weekly study group more than 6 people is unlikely to be very efficient (and hard to schedule! ).
