Hi Sameer,
There are so many institutes in Hyderabad, but the authorized one is Siemens. But again, I don't want to suggest you go to an authorized institute because these people only provide material. If you want that material, you can also get it at Ameerpet xerox shops. Tell them you are looking for Siemens material. Now, come to the point, if you want to go for SAP, be prepared with a PC at home. Because once you go to the institute, you will do theory and practicals. But according to me, I suggest that when you come back home, do the practice. It will be fruitful for you, okay? You can do one thing, find a good faculty, not just an institute, okay? So that according to that, you can go to that institute, alright? However, even I have done it from Ameerpet. After joining, whatever problems I faced, I don't want them to be repeated with you. However, I will try to find a good institute for you, okay? If any details are required, email me at priyananu1@gmail.com.
Sorry for the long mail, but that is the fact.
Regards,
Priya Jain
