As a matter of fact, most of our graduates go on to advanced education. As a science major, you will have few electives. If you delay taking these introductory courses in Biology and Chemistry, you are out of step with the rest of the class from the very start. That way you will be assigned to one of our faculty and get the best possible advising for your major. Freshmen sometime rely too heavily on their native skills, which got them through high school near the top of their class.
College requires more work, more personal initiative, and better time management.
I recommend that you have regularly scheduled study periods and keep up with your reading and homework. With regard to abilities and attitudes, I find that people do well at things they like to do, and they like to do thing they do well. You are obviously involved in your field. I wonder if you would add a personal opinion about what you see to be the advantages and disadvantages of entering your field of study. Our students, faculty, and staff are bright, hard working, interesting people.
