Enter them under a program you create. It doesn't actually have to run as a program, but you've got limitless space to store stuff.
EDIT: And programming with them is easy as hell. If you can find somebody that can, (and can keep their mouth shut) they could write one for you in like 10 minutes.

Or, you could just spend a few hours making notes of the forula you need, learning them and doing a fw practise questions. Cheating in tests does not make the final thing easier. A bad mark will be a kick in the backside to get working, and a good one will show you know it well.

^^agreed. work hard. but if your not cheating your not trying your hardest. still study and still learn the stuff, but having a cheat sheet with formulas palmed can save your grade.

I'd rather fail than pass by cheating, knowing that I don't actually know half of what I just did on the test, but that's just me.

ok to the people that keep on saying learn the formula i have to learn all of this:


Variable cost per unit= (Highest cost – lowest cost)/(Highest # of unit produced – lowest # of units produced)


Fixed cost= variable cost per unit * lowest or highest # of unit produced – the total cost to make that # of units

Contribution margin (per unit) = average price- variable cost per unit
Contribution margin ratio= Contribution margin per unit/ unit selling price
Contribution margin (in dollars) = Sales- variable costs
Break even point in units= fixed costs/(sales price-variable costs per unit)
Break-even point in dollars= (fixed cost)/Contribution margin ratio in % form
Margin of safety in dollars =(actual sales-break even sales)
Required sales= (fixed cost + net income)/ (price - variable cost)

Margin safety ratio= Margin of safety in dollars/ actual sales

plus other formulas. I also have other tests that i need to study for. I would rather spend my time studying for my business law test instead.

edit: The professor is letting us use a 3x5 note card as well.

Erm... That's nothing.

For each of my end of semester exams I need to learn 5 pages of formulae for each module I'm doing (three modules), plus definitions.

It would take you 30 minutes to learn all of those off by heart, so don't be so lazy.

Can't you just write all of those down on your 3x5 notecard?

Well hopefully your teacher doesn't go around the classroom making people delete all the info in their calculator before the test, if he does that you're screwed.

Lol. You can't learn business finance 'formulae'. You should be glad you don't do maths. Besides, most finance equations are common sense.
#19
back in my emo scene kid days I just wrote the formulas on my legs through the holes in my pants
Matt: it wouldnt really be a gainer since ur just going straight up
Me: i'm going over the spine
Matt: yea i know spine transfer
Me: frontflips > backflips
Matt: or in ur case it could be called broken spine transfer if you fall hard

You didn't answer him either.

I just wrote some on the inside of the battery cover. Didnt use them though.

But if you don't know them, you won't be able to use them under pressure in an exam.

Make sure to group them, this way they can't be deleted.
(ungroup them if you want to use them, if you didn't know that)

depends how they clear the computer. if they go to the right menu they can completely wipe the whole calculator.

if they just look at the programs and delete them, yea that will work
