So applied for my EOI under skilled migrant category ICT Customer support and technical advisor and was selected. I've since been told my degree is not relevant so I cant claim points for it. My case officer has asked for more information from me as he is saying I don't have enough points. Can someone help tell me how many points I might have for the following

Skilled employment in Auckland ( think this is 60?)
5 years skilled experience in Auckland (not sure how many I claim)
10 years experience in UK 7 which is skilled (not sure how many I can claim)

I'm 42 ( i know this is 20 points)

My degrees (information management) I am told is not relevant as it's not on the list but i've been told I can try and have this approved as I think some modules could be relevant but even if it is approved case officer still might decline my application.

Is it possible to apply for residency bases solely on your work experience? I wonder if i have enough points.

Also do you think it would be easy to argue some elements of my degree being relevant but wouldn't this have to be done officially or can I simply put my case in my cover letter.

I'm soo confused right now and have a million questions :/
