Personally I started learning using the examples and documentation in the NetSuite Help. You might be able to do the same and make use of SuiteAnswers, the NetSuite User Group forums and here. There is also a good book out there, I'll see if I can find the name of it, I think it was mentioned in this thread a while ago. @shadman Ashrafi Have you completed any NS run courses?

no i have still not done any course on Netsuite.
