Hey guys, just came back from the A+ core exam got 419. I thought i had it down but i guess not...i feel so bad

. Hope to take the exam in the next month maybe. Does anyone know any good websites that offer any free practice exams other than this one?
I plan to use this websit a lot ...it is great, really like how everyone is in the forums(nice, informative helpful), and the notes are great too.
Any tips for studying for the exam?
Thanks
