If you schedule does not allow you to sign up for CHEM 499, you can do research on a volunteer basis, working when your schedule allows. Consult faculty members about this possibility. Most faculty are willing to work with students at any stage in their academic career. In many ways, the earlier you start, the more rewarding your experience will be. While most A and B students do make fine researchers, I have seen several borderline students excel in the research lab.
Many students are more motivated to do work in the laboratory than attend lectures and take exams.
You will be listed as a co-author on any paper that includes your research and is submitted for publication in a professional journal. In some cases, you may be asked to write portions of these papers. These are big resume builders. Typically, presentations are 15-20 minutes in length, and your faculty research advisor will work with you in preparing your talk, along with the visual aids. Talk to at least three or four faculty members about their research projects.
