I am looking to learn SAP R/3 cources ,right now I am working as SAP B1 Technical Consultant. Which is best for me?

Look both are best but it all depend upon u b'coz u are aware in yourself so it doesn't need to tell u the scope for any one in today's scenario both in demand. ok. So, its all up to your interest b'coz interest is more important for achieving a mental peace as well as marvellous career.
