It is very important. I am looking for an online course 8 week long equivalent to Excelsior IT360 OPERATING SYSTEMS online. I checked with local community colleges but nothing online and weekend classes not until June. I need to start this course by May 1st and finish in 2 months. EC is offering it in 15 week term which will overlap with my other courses. so, if any one knows of a an insitute please let me know ?
