Working on A+ Cert myself. It is best to take it one exam at a time. Don't push yourself too hard to attempt both exams on the same day. Give yourself some time between the two and study specifically for one, then the next.
I have also found that, in addition to training videos, you are able to buy practice exams that are worded and built as close to the real exam as you can get. Since the entire exam is multiple-choice, studying practice tests in the same format should serve you well.
