Biology

I am taking a biology class this semester. The lab for the class was rather easy. However, I am doing terrible in the class. I attend every class meeting and take notes but I just can't seem to do well on my tests. I have received extremely low grades on my tests and fear that they will impact my final grade drastically. I study and try to prepare myself to the best of my ability but I just can not seem to get it together for this class. My teacher is really nice but confusing at times. Maybe I just need to study more. I just hope that I can make a C or better in this class or I will be stuck retaking the class to better my chances of getting into nursing school here at southern.
