if you need practice then.... practice :p we can't give you time to practice
but yeah, just use google, you'll find this site, along with gnomonlogy, digital tutors, highend3D and buzz3D
but i'm still going to tell you to do the tutorials in the maya help files
because what you will find on the net are for older versions of maya where the menu system is changed. and if you start fresh on old tutorials you'll be wonderings where the non-existant modelling menu set is when you would know the answer should you have done relevant tutorials
just thought i'd give you a heads up if you didn't know that already
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
