They may appear to be 'easy' or 'lenient' at first glance, but don't let their friendliness fool you. Professors are hired to educate students, not applaud mere effort. If your professor applauds your efforts by giving out high scores, even if you only earned no more than 60% in actuality, then he/she's not doing the job; either that or you're taking a science/math course!* hahaha...
Anyways, I've had countless professors who were really nice and laid back during lecture, only later to find out they were, in fact, strict graders who didn't cut anyone slack when it came to subtracting points on diagrams, calculations, or essays. College can be very deceiving at times so let this be a warning.
*If you didn't get that joke about science/math thing:
True, in some instances it is possible for one to slack off and get by on cramming things the week (sometimes even the night) beforehand and still get a passing score on your midterm thanks to crazy grading curves set by the lack of studying from your peers, but that's a very low standard for yourself if you depend on things like that. This dependence on super-skewed curves causing people with a 50% getting A's occur a lot in college, namely in science courses and a few math courses. However, getting by without really knowing your stuff will not last long, because like in high school, everything tends to build up into a pyramid of knowledge. You can't really get to the top unless you have the basics down. Especially if you major in science/math, because most of your required courses come in a series spanning the whole school year. Humanities and social science majors maybe the same, but I wouldn't really know...the ones I took for breadth requirements were only one quarter and you were done.
2. College IS harder than high school
Lots and lots of people, typically freshman, say that college isn't as hard as they thought it would be, and might go on to say that they've had it harder in high school. Why do they say this? Let's see....because they're only freshman!! (I'm ruling out the rare geniuses, of course)
Aspects of college which often mislead freshman:
a. The fact that it's the first time they can control they're own schedule of classes,
b. "I spent way more time in hs studying for ap exams than I spent doing hw for college classes"
c. No more 7-8 hour school days! so much time on my hands, right?
Usually you start with the breadth classes which sometimes actually aren't easy. But for the most part, a lot of new college kids straight out of AP classes think they are the shiz because they remember how to do derivatives, or get integrals, or are experts at mLa formatting, and therefore are misled to think college is a breeze compared to their hs years. The fact is that these kids haven't reached the "hard stuff" yet. In response to the a, b, and c reasons listed above, sooner or later you'll find out that juggling your time wisely is a difficult task that can make or break you when it comes to final grades. Even if things are a breeze, a lot of people end up partying wayy too much and lose sight of why they are really in college. Procrastination begins, then crazy all-nighters just like in hs, except the material is covered at a much faster pace so that means more work and more stress, = harder than hs.
bleh you can tell that I suck at English. lol.
anyways, that's all for now.
1. Never underestimate your professors.
