The midterm exam is meant to help assess you learning so far.  Do a conscientious job preparing for it.   It is your best indicator of how you will do on the final exam, and your best preparation for it.

Students who have worked independently on their Science 20 Course usually have exam results about equal to their course average.  If they have not studied well, it will be closer to the grade achieved on the unit review.

Students who have not worked independently enough, or relied to heavily on the internet on their assignments, score about 15% below their unit review marks.   If you think this was you, prepare very carefully for the midterm exam.

Prepare for Unit D by using the notes you have prepared.  If you did not make notes, use your Unit D Review Assignment wisely.  If the review assignment asks you about the Pyramid of Numbers, make sure you review the Pyramid of Mass and Energy pyramids, too.

Prepare for Unit A by redoing questions on all of the skills that you made on during Unit A Review Assignment.  Relearn the skills by doing!

The Unit Reviews are the best tools you have to prepare for the midterm exam.
