Can I use my A+ 300 series notes and books for the 600

HI,

First time poster, I passed the old A+ hardware (220-301) right before expiration, but didn't passed the OS portion in time. Since then I've been very busy, but now I'm ready to retake the exam. In studying for the new 600 series, can I use my study information for the 300 series? I ask because I went through Techskills and I still have access to their study guides, I don't want to study information that will be of no use to me. Thanks.
