Signed up for NET+! Already have SEC+. Any Tips?

I already have Sec+. What are some similar topics that are covered in both? I have scheduled this for about a month and a half out. Should this be enough time to prepare ? I have the Mike Myers Passport 4th Edition as well as the Network + Guide to Networks 5th edition by Tamara Dean. Should this be enough to study? Anything is always helpful! Thank you!
