Physics GRE Discussion Forums

I am in the last yr of Bachelors program in IT.
No physics in curriculum.
Desperately want a good score in PGRE.
Will also be doing a project in physics this yr hopefully.
Is the prep time till april enough for a student like me?
Please suggest me some book for mathematics needed for physics.
Thanks..

Mathematical Methods For Physicists by George B. Arfken is a good one after reading calculus.
