<p>I took calc III, diff eq, and linear algebra a while ago. I don't remember much AT ALL. I mean I used the augmented matrix operation I learned in linear algebra to help me solve systems of equations, but beyond that, I really have no clue anymore. I remember vaguely that 1/s turns to e^t in Laplace Transforms, but I have no idea what that means.</p>
<p>I feel like this stuff is going to come back and haunt me. I asked a couple of friends, and they feel the same way. In your experience, do these things come back right away? or does your brain basically wipe itself clean after finals?</p>
<p>I couldn’t pass a calc final right this minute for the life of me, but give me a day or two to catch up, and I’ll probably be fine. </p>
<p>But yeah, all of that stuff you listed above is actually really useful and good. You will need to know all of that in most Engineering disciplines. </p>
<p>One of the reasons that I try not to cram, btw.</p>
<p>I always think everything is erased from my memory, but when the info is brought up again, it jogs my memory and I actually know quite a bit. Of course there are some things I need to brush up on again, but its always easier the second time around.</p>
<p>Biology and chemistry are pre-reqs to all of my other courses. Can’t say I remember many specifics from either. I’ll probably end up with a near 4.0 this semester, so can’t say its done much harm, but it might depend on your particular major.</p>
<p>The way I see it is I pack all of the information in my brain for 3 days before the test and when I get the test in front of me, it’s like my brain just vomits all of the information on to the test. </p>
<p>So, yeah, the information pretty much escapes after I hand it in. It’s like a burden off my shoulder. There are exceptions though, like math. That remain in my brain forever until you come across it again (as it should)</p>
