Can't hurt to frantically run around (the lecturer could have one as well) but generally people won't have them unless they need them then and there. Doing all the working out etc and follow through points can help?

You surely shouldn't be using a graphing calculator for an exam? Also, I know plenty people from my maths undergrad who'd bring two scientific calculators on exam day just in case. I hope you found one!

Who takes precalc in college? You don't necessarily need a graphing calculator for that, just a scientific one. Lots of math teachers are bitchy and won't let you borrow one if you forget yours.

Exactly, there must be someone you can borrow it from. To everyone, you need a graphing calculator for pre-calculus. Not a regular. You could do without, but the immense time you would lose will only let you get one question right. Your name. (Exaggeration) I'm thinking you're a high schooler since Pre-Calc isn't a necessary course for college. Just ask someone who takes trig or geometry or even algebra since thats when they require you to have one.

I forgot my calculator for my Calc test in College once. I went to the math department and asked to borrow one. I just had to give them something to hold until I returned it so I gave them my car keys.

Honestly, I couldn't imagine doing Algebra 1 without a calculator, let alone any higher math. Physics is even hard WITH a calculator. I feel sorry for OP on this one, FYL.

39- In my AP calc class, we are never allowed to use calculators, because, as you said, the point is to be able to be able to do everything on your own. However, just like OP, we were allowed to use calculators in my pre-calc class, as the cosecant of 7, for example, is not something that is easily calculated, and spending time calculating it is just a waste. Instead, we were permitted to use calculators to calculate values such as cosecant of 7, but we had to show all of our work. I am sure this is how OP's class works too.

In IB math exam is divided into three papers - you are allowed to use a graphic calculator in two of them and you can;t use one in the other one. Assessing different skills, basically. What is wrong with using calculator anyway? It's the thinking that counts the most, the calculation itself is of secondary importance. (Sure, the misplaced comas and so on are important in the real life projects, but for the exams? One point only for the correctness of the result, the rest is how you come up with the answer).

How the bloody hell did you get "hate the America" from my post? :P I think it is a very advanced country and many of the best universities are there. I've been there countless times, both for work (yes, legally, in IT field) and pleasure. Not everyone out there is to make fun of your country, so please don't give people any more excuses.

Can't resist... must resist... It's a sure sin of memory loss if you forget your calculator, OP. I mean it's pretty irrational to forget that it is an integral part of your success, you'd think the thought of bringing it with you would be recurring. It's pretty primitive of you to do this with mental maths, the numbers won't add up, and it's just plane silly to try.

Your graph just went negative for a little while, now it's limit is tending to +infinity :) I wonder when all these a-sin-ine math jokes of mine will come to their maximum...

I feel like if I wanted to use the word "trifle" solely for the fun of it, I'd have come up with a hell of a lot more entertaining sentence. As it is though, you're wrong. Trifle isn't that interesting of a word anyway.
