    More importantly, how does your VM have a scroll bar on it? What magic is this?!

    It was pyinstaller that was bugging out. On Linux, since the executables are different, it had issues freezing and gathering the right ones, more specifically the C based modules that form the base of graphics libraries. The dev version has fixes for this. However, I have encountered several errors where one coding practice works great on one platform, but causes overflow errors and other bad things on others. So, yeah.:P

    Python is cross platform, what kinda bugs were you seeing?

    Lol, so I finally got my program to compile on Linux:P I had to use a development version of pyinstaller because of a bug that drove me nuts.

    Yeah, I'm not doubting you mathematical sense :P
    The censorship on this website though, can't say that 4 letter synonym for digestive excretion.

    When I mentioned calc, I was just saying I was good with math.:p Now I see what you are saying. I thought you just meant (essentially) plot the points on a graph and then raise the all points equally until the lowest is at 60.:p

    I feel like you didn't read what I said, but rather disagreed and then echo'd it with more words :P

    When I say linear curving, I'm referring to a 0 slope, a raise by a constant percentage. That may have been where we flew off.

    Anyways, the Profs tend to curve the class average to some value, then apply the increase everyone's marks. That is to say, they curve a variable amount. So in a class of say 20 students, the median was 60, but the average was 50 then indeed the lower end marks get affected the most. However, if the average was say 60% and a median of 45% (kinda drastic, but just an example), then you'd notice that the curve applied to the class average is very very small. In the end the guy who scored 10% in this case can (probably, depending on the distribution) not hope to get over 20%. That was probably the ♥♥♥♥tiest explanation ever, but you get the idea.

    I've taken calculus pretty much every year so far. I've studied from integration to real analysis and number theory for my program requirements (even done some linear algebra stuff, design, analysis of data, probability & statistics) . This grade curving problem is more like applying a function to a set of grade distributions than it is calculus.

    Not really, grading on a curve means that you need to bring all grades below 60 up to at least 60, so there will be a proportion involved. The worse your grade, the more points you get back, meaning that a score of 10 will get +50 while a score of 90 will get +2. (I'm a calculus student in high school man, I've got this math stuff.:P) Obviously this won't look fair to the guy sitting on top, but it still gets the job done by essentially removing the fail range. So, your score, by proportion would probably get +10, bringing you into the C range, which is a lot better than the D range. If you grade linearly, then you are grading on a line. I have never seen a teacher grade on a line, it is always a quadratic or high function.

    Well, unless you do it linearly, there is no way to grade curve "fairly". Everyone with a unique grade will receive a different amount of free marks.

    That is why you grade on a curve, not a line.:P There are ways of doing it where it is evenly distributed. In fact there are whole websites dedicated to curving formulas.

    Yeah, because despite the large majority doing horrible, there's always those 1 or 2 guys who score high enough such that a linear increase would shoot them over 100%.

    That is a terrible way of curving.... Jeez

    Not always good, sometimes I score a 65 and the prof curves up the grades for the average to hit 60%. I gain nothing from these, but I still retain my bad mark :D
