In order for your Gradebook to accurately reflect your grades and course %, you need to insure that certain settings are made:

On your Gradebook page, at the far right (or down at the very bottom, depending on your screen size), there is a listing of your Total % and Letter Grade [such as Total: 83.37% (B)]. Below that is a table that shows the % contribution of each of our assignment groups (iClicker points, 10%; Lecture quizzes, 10%;, etc., same as found in Course Info). Below that table is a checkbox labeled "Calculate based only on graded assignments". If you CHECK that box, your course % will be based only on what items you've actually done at that point. If you UNCHECK that box, your course % will be based on all available assignments at that time. For most purposes, you should CHECK that box, so that your course % will be based on all materials that you have so far submitted. Otherwise you will include scores of '0' for items not yet submitted, which will bring your grade down unrealistically (unless you've failed to turn in a required item, in which case it should count as zero).
Mastering Biology (MyLab and Mastering): Scores are given as points in your Gradebook (out of 20, 25, etc.). However, the Total points possible is calculated based on possible points for all published Mastering assignments (even if due date has not arrived and even if you have not done that assignment). So your % for Mastering assignments may not always be accurate, depending on how much you've done and how much I've published. This can influence your Total course % as listed on your Gradebook page.
Also be aware of the "What if..." feature of the gradebook, where you can, for any upcoming grade put in a sample score for yourself and see what effect it would make on your total grade. Of course this sort of analysis makes more sense as we near the end of the semester.

Notice the difference in Total % at upper right for checking and unchecking the box (at bottom right):
