Why I became a Biologist:

Because I’m a nerd… that… and never ending sense of curiosity about living creatures.

Recommendations for student success in my courses:

Do the assignments; pay attention in class and study for the quizes. Fifty percent of your grade is based on assignments, group work, and quizzes. You do this; the exams will be a piece of cake.

What’s great about the Biology Department at San Antonio College?

The small classes create a rich learning environment. Instead of a number you are treated as individual. Plus… you get me as a teacher.

Calculate your current grade:

Click on the icon for the class you are attending and download an Excel Spreadsheet that you can fill in to see your current grade or perhaps what you need to make on your remaining tests or the final to make the grade you want.
