A+ certification anyone?

im studying to become A+ certified, i am pretty dang close to finishing the book CompTIA A+ Certification by Mike Myers. but i feel like i have already forgotten everything i read! ive never studied before in my life but i need some pointers

Any body whos going for or has gone for and passed A+ cert any tips pointers? whats the test like?
