<p>^you need to do research if you want to get into grad school but if you don’t you can definitely not do any your undergrad years and graduate fine. </p>
<p>There’s really no set formula for finding understanding and helpful professors. In general younger professors can be more helpful but I’ve definitely seen exceptions. I would suggest meeting with professors and assessing how friendly they seem in person as well as asking people who might know how it is like to work in their labs. </p>
<p>I highly doubt that there are top colleges with more understanding profs than others. They all probably have a roughly equal distribution…</p>
