Seo Training - Clroom type?

I am interested in doing a course in SEO and related certifications in mumbai. Can anyone help me with the right info. Most of people available online are sounding unreliable and have just half or open ended info on their site. Like IMRI, VAMA infosys etc. They just seem to have the reading headings on their site but do not have the appropriate info. And most of them are not willing to do clroom training. So pls help.
