I just passed my A+ os and core yesterday, my score was a 722 on both of them. Advice I can give to anyone taking them is to Study. Spend way more time studying the A+ books rather than the test from testking or another one of those companys claiming to gurantee you pass. Most of the questions had to do with the recovery console and making boot disk.also know what the winnt32 /checkupgradeonly command is for and what os its for. I had 3 questions on it. I used the mike myers a+ (all in one) 5th edition, i purchased at borders and it was a great study guide.
