Really easy:

Full-time MBAs: feature daytime classes during the week. It's hard to manage working during a full-time MBA program.

Part-time MBAs: can feature a variety of scheduling options, depending on the program. For instance, in USC Marshall's part-time program you can choose to attend classes on either nights or on Saturdays. Designed to work around the schedule of busy, working people.

Executive MBAs: usually aimed at people with more experience than part-time or full-time MBA programs, but this can vary. Also offers a variety of scheduling options. These often are set up in a modular format, where students take blocks of classes during one compressed period of time. For instance, students in Oxford's EMBA meet for one-week sessions 17 times over 21 months. Others, such as Duke's EMBA program, have weekend options.

Hope this helps!

Actually I will study Executive MBA at maastricht business school through RITI in Egypt, and they provide Executive MBA. I believe this will be suitable for me as I have 10 years experience in the market.

Thanks really for your support!

That programme is taught by Maastricht School of Management, not the (more prestigious) University of Maastricht business school.

Yes I know, however it is AMBA Accredited and it is considered the best one in Egypt with a reasonable fees.
