Unfortunately the market for these types of applications is quite limited. I'm not sure what student Docket does but they had a special with Cram ($15, which I did buy.)
Looks like your best bet is probably going to be wait till they have another special or find a coupon code if they accept them, you might want to check 3rd party software sites as well.

Just think about how far BlackBerries have come from then till now... And what else is coming.
