If you need 2,000 calories per day and you regularly consume 2,500, you'll
a. lose muscle mass.
b. gain weight.
c. maintain your weight.
d. lose weight.

B, you'll gain weight because you're exceeding what you need.

Along with the credits thing it could also affect your health in a type of way. you need to get out the house or off the computer and interact with people. if you stay taking online classes and are not going outside and socializing that could affect your health or your mind. your mind will start to form into you being alone and you would want to be alone over anything. so public or private school would be good because there is people around you to and support you.

Lightning would be your answer
