One proven approach to goal setting is to make your goals SMART.
S - Specific
M - Measurable
A - Achievable
R - Realistic
T - Time-bound
1. Find a quiet, well lit place to study that is free from distractions (cell phone, television, non-studying friends).
2. Choose a comfortable place to study -- but not SO comfortable that you get sleepy!
3. Find the time of day that works best for you and make that your regular study time, if possible.
4. Form a habit of reading over each day's notes while they are fresh.
5. Bribe yourself! Upon reaching your goals, reward yourself with something fun.
6. Take frequent short breaks -- like taking a walk to energize yourself.
7. Alternate between studying alone and with a group. Working alone can be good for mastering concepts and information, while working with a group is a great way to test for true understanding.
