I am very interested in pursuing the part-time or on-line MBA program in the near future. As I cannot take an extended leave from my work, the full time MBA is not an option for me (at this time). So, it would be the part-time MBA (classes in weekend) or on-line MBA (with short residential periods during the holiday season). The programs should be conducted mainly in English. My areas of interest are marketing or general management (with strong international elements to it). Which university would you recommend for MBA programs?
