Ask this person for help first before asking me. This way I will be available to help more students. I usually do not have time just before class to help with assignments. Lab partners should look out for each other. Also relay any announcements to your lab partner, that your lab partner may have missed.
Biology is much more than memorizing facts.
A key element of biology is the understanding of principles and concepts. Please ask questions until you understand the concept rather than just memorizing a list of facts. Biology is a fascinating subject and can teach you so much about the world you live in. It reinforces the material learned in class, prepares students for upcoming classes, teaches them to work independently, promotes students responsibility, and aids in evaluation of performance. It has been demonstrated in scientific studies that consistent homework increases learning.
