mathematica for students

Hi i tried a trail version of Mathematica around 12 months ago and am now thinking of buying a copy but i can't find the version i had last time. The one i used before had graphical interface for alot of functions to make it easier to use but the trial version i downloaded today just seems to have a command line interface.

any ideas of where the grpahical interface is? i downloaded the student version both times

thanks.

 

Thanks ye that defiantly makes it easier. found the product i used last time it was called calc center 3 (also form wolfram) but i can't find it anywhere now on the wolfram website which seems odd.
