I’ve been a professor for about 20 years and I can try to answer some of your questions and give some advice for a successful transition to college and a successful college career. I can’t speak to a STEM major specifically.
Most professors will use the first week to go over the syllabus, but not all. Be prepared for both.
Make sure you stay on top of what you need to do to graduate. Know what the requirements are for your major and for the University. Know what courses will satisfy those requirements. You will hopefully have an advisor that is knowledgeable and helpful, but that advisor will likely have a lot of other people they need to take care of, so it’s ultimately up to you.
Use a calendar to keep track of all important dates. At the start of the semester, look through your course syllabi and schedules and write down all due dates, scheduled quizzes, exams, papers, and presentations.
Also, know the dates of administrative deadlines and windows. That includes when you can register for courses, the drop-add period, the last day you can drop a course without penalty, financial aid deadlines, etc.
Read the course syllabus carefully for every class at the start of the semester. Know the requirements of your class, how you will be graded, the late policies, attendance policies, etc… One pet peeve of many professors is that students ask questions about things that are clearly laid out in the syllabus.
However, don’t be afraid to ask questions (even if something is in the syllabus). Ask for help and clarification as needed. Most professors will be happy to help. Sure, there will be some who aren’t, but you still need to ask questions if things are unclear. I tell my students I can’t help them if they don’t ask for help.
Don’t wait until the last minute on anything. I know this is a tough one in some cases (we’ve all pulled all-nighters to get papers in on time), but do your best to give yourself a buffer as much as possible.
Get to know at least one other person in each of your classes…hopefully more than one. It’s good for study help as well as for getting information you missed if you can’t make it to a class meeting.
Know what your professors are looking for in assignments and tests and then give it to them. Read all instructions carefully. For written assignments or test questions, that includes all the formatting guidelines (font, spacing, word or page length, how to cite your sources, etc.).
Listen carefully to what your professors emphasize in class. If you don’t do as well as you would have liked on a test or writing assignment, ask what you could have done better. This is especially important at the beginning of the semester. Try to figure it out as early as you can.
Make use of your college’s writing and study centers. Even if you’re a great writer and very organized, see what resources are on their website.
Be excited about college!
