excel tasks for free

[fantasticromantic]

Hi people, soon I'm going to start with a new job where my excel skills will be tested. So for the last 5-7 years I wasn't much in contact with excel and now I need to freshen my knowledge. Anyway I am willing to do someone else's work for free (just as a practice)....... will perform excel tasks for you.
Just give me reasonable homework.

Anyone?
