This is a quick post:
If you are a student and you need to take the CompTIA A+ certification very soon, I recommend the above link. It gives you a discount for one test. The voucher can be used for the 901 or 902 test.
If you are no longer a student and need to take the test and you still use your student email, then the discount voucher will still work.
Just one problem, this is only for one test and nothing more. So no books or pretest. There are tons of free PDFs on the internet and free YouTube videos that can help you out if you are a bit rusty.
Also, keep in mind that in 2019, CompTIA is going to introduce 220-1001 & 220-1002 series. So it means that 220-901 and the 220-902 are going to disappear and the voucher will not work after July 2019!
Anyway, happy New YEAR!
