Online course to prepare for MBA

I find the online mock series of TIME to be the best. it is comprehensive and very nicely structured. Also if cost is a factor then TIME is comparatively more cost-effective than many other series out there. There is also an added advantage of the fact that there are a lot of TIME centers around the country, so if you are stuck somewhere or there is a glitch on your account, then the response time is much faster than any other series.
