i am currently about to go for an interview after christmas but need to create a portfolio is there anybody who can tell me how to do this for a 3D animation course. I realy need help

This should be under General, not Technical.

Rushing a portfolio is like practicing for a concert the first time the night before. The entire point of a portfolio is to show work you have done. Hopefully you have some work you've done, with some design, modelling, animation - it really depends on the course you're applying for.
