bio final study guide 2015

This is the information that will be covered on the FINAL exam in JUNE.

We suggest that you start early and work on this a little bit at a time so you don’t have to cram. Plan to have it completed by May 26th.

We will go over certain chapters on certain days (schedule will be given in class). These days will be most beneficial to you if you have already completed the sections and come to class with questions or things you would like us to go over. We will do practice activities and answer specific questions during class time. In all honesty, we will not have enough time to go over every single item in this packet (and you probably don’t need us to!).

We are available after school for extra help. Check with your teacher the day before you want to come in to make sure we are not in any meetings.

Good luck in preparing and let us know if we can help you with anything along the way!
