I did much the same by waiting to the last minute to study even though I had the study material for months.
I took a practice test, then spent the majority of my time boning up on my weakest subject. (Math of course). I spent a short time reviewing Latin roots, prefixes and suffixes to enable quick word recognition for the vocabulary section. A review of the solving strategies for the types of logic questions that would be asked wrapped things up for me.
If you don't have a major problem area like I did, I would still recommend dividing up your study time based upon your strengths.
Good Luck
