I completed my MBA with Finance & Marketing specialization. I had job experience of 2 years in marketing. Now I had joined in another organization in Finance section. For my career development, is there any short term courses are available? And they must be parttime. If it is possible, up to maximum level they must be online courses.

There are tons of short-term courses available out there. However, every school is different in what they provide. I think what you really need to be doing is looking at sites where you can put in what you are looking for and have it spit back out what schools might have that available. If it's online, there's a LOT of choices about where you can do this.

I don't have a specific suggestion of a site to go to, and that is because this is an accounting forum and not an education forum. We have an education forum, with sub forums related specifically to colleges and such. They might have a suggestion for you.

(You could probably put "online universities" into Google and see where it gets you.)
