Your Progress and Final Thoughts

If you scored between 0 and 7 questions correct, you need to study the entire guide again. Obviously, you are lacking in mulitple areas of the security+ examination and could therefore benefit from reading all of the subject areas in depth.



If you scored between 8 and 11 questions correct, you should take a close look at the subject areas of the questions that you missed and carefully re-read and review the lessons in the guide concerning those specific areas. If you took the exam today, you would probably not pass with this sort of score.



If you scored between 12 and 15 questions correct, great job! You should probably glance over some of the questions that you missed and the corresponding guide article, but you are most likely ready to move on to our cram sheet. If you took the exam today, you would likely pass it.
We wish you the best of luck in your pursuit of Security+ certification. Be sure to check out our and take plenty of practice exams! We hope you do well.
