<p>I cannot attest wrt to physics, but here goes Bio stuff:</p>
<p>I'm a junior neuroscience major. I went through all of this and have seen many others struggle for various reasons going through this. So, I will try to a) answer your question, but also b) to give some advice for people considering Bio at UR. </p>
<p>1) All core courses for all Bio sub-majors (e.g., neuroscience, biochemistry, molecular genetics, etc) are the same. All B.S. Bio majors need to take Intro Bio, Chem, Orgo, and Calc. </p>
<p>That said, you and the rest of what seems like everyone else who goes to UR, will be in the same classes for the first year+. So, first year Bio/Chem/etc classes are big, test grades are curved to the performance of the rest of the class (except in BIO112), and attrition is high. (PS - If you chose to come here, and have a 5 on AP Bio, DO NOT take Intro Bio 110, but instead take Intro Bio 112 your first semester - it's smaller, professor Platt is the man, it is a lot more interesting that 110, and you get all of the test questions beforehand). </p>
<p>2) Some freshman come in with this predetermined I-am-triple-majoring-science-hardcore-premed-only-don't-have-time-to-talk-to-you-because-I-must-go-study-24-seven attitude that does nothing but alienate them from others and, quite frankly, puts them in a bad situation academically. These are the people who often end up struggling, because they are a) overstressed, b) spend all waking hours in the library studying, and c) attempt to make ZERO social (and academically advantageous, might I add) connections with others. Now, it is not that these people are dumb, it is that they are miserable being a science major, and as a result, end up struggling and stressed out (some also don't shower often - eww)</p>
<p>Please, keep an open mind with respect to classes/majors when you get to college - wherever it might be. A little fun time, social contact, and (I actually DO MEAN THIS), not taking all of your classes with such seriousness goes a long way! </p>
<p>3) With these preliminaries aside, now to answering your question:</p>
<p>No, most people are not cut throat and most are pretty chill and fun to talk/hang out with. It is the show-up-to-class-30-minutes-early-to-get-a-front-row people, as we sometimes call them, that are the most annoyingly and intolerably competitive. These are the people who ask questions for the sake of hearing themselves speak. These are the people who will cover up their lab notebooks in lab so that you "don't per chance see what they wrote". These are the people, in short, you want to avoid.</p>
<p>All others are very chill and open. Multiple times I have helped other students with classes I already took/was taking. When I was a freshman, on multiple occasions I received some help/advice from older people. If you try to not be like someone I described above, upperclassmen might feel kind enough to share past notes/other things I shall not mention on web forums from classes they already took. </p>
<p>Hope this helps.</p>
