  • CAD (Computer Aided Design)/ CAM (Computer Aided Manufacturing)

  • Ultra ATA, SATA (Serial ATA), ATAPI (AT Attachment Packet Interface)
  • AMR (Audio Modem Riser) and CNR Communication Network Riser) slots

The new exams have also went from an adaptive format to standard exams. Scores range from 100-900.

The 2006 Edition along with Exams 1-10 at this site are specific training for these new 220-301 and 220-302 exams.

We have setup this site and one at geocities.com/aplus_practice_exams as a mirror site so you may be switched back and forth to relieve bandwidth problems we encounter due to high traffic volume. These are the two and only official Aplus Omega sites. The questions are the same at either location.

To begin our exams you should have a Netscape 4 or Microsoft Internet Explorer 4.0 or above browser with "Javascript enabled" which operates the timer and grades the exams.

The notation win 9x refers to either win 95 or win 98.
