Tnq For the reply @legalfalcon i have one more question now.You don't need to explain any thing. The ECA will get you points for the education and your work ref job duties and NoC selection will get you the points for the work.
Its as simple as that. If there is any confusion or something that is not clear needs explanation.
Before ita i kept 2173 as noc code
But my job title comes under 2174. I got ita and can i change my noc to 2174 now.
