Hi Nikhil,
please understand one thing, untill you will take any risk in your life i don't think you will gain anything better, so i think don't go through negative thinkings. As you have planned for SAP MM functional module , you can search for any authorised training center at Google nearby you, but please understand one thing, taking a certification alone never gurantees a job in sap world, so if you are thinking that you will get exposure by doing certification , its not dear.
So, what you have to do is, learn sam mm module at training center and then you should search job in any manufacturing or in major infrastructure company, search at Naukri.com (because they will negotiate in terms of experiences with respect to IT companies), one you will get any ggod job, work hard there so that you are able to play with mm, then you can switch towards any major IT company.
If you have any dought, feel free to ask.
