The A+ exam was just updated to the 220 1001/1002. Below is what to expect.
The CompTIA A+ Exam A+ exam is broken down into two exams:
Total examination costs =330$ US (varies depending on location).
To become CompTIA A+ certified students must successfully complete both exams
You have 90 minutes to complete the CompTIA A+ Exam. However, once the exam has started there are no breaks given unless there is a malfunction with the test.
The CompTIA A+ exam has a maximum of 90 questions. There is a myriad of questions types such as:
The passing score for each test is as follows:
Students must recertify every three years. Students can waive recertification by enrolling into CompTIA’s continuing education for an annual fee. Another route to recertification is by simply acquiring a higher level certification. For example, a student who is A+ certified, can get security+ certified as well. In doing so they not only obtain the Security+ certification but also renew their A+ certification.
