I am in the same boat, after extensive research and working...
In my opinion, your preceding degree 2 years program would be equal to 2 years diploma and MCS in conjunction with your last degree will be equivalent to 16 years undergraduate degree (BAchelor's degree).
This way you'll be able to claim points for two to or more degrees.
What was your preceding degree? (Degree you acquired before MCS)
My friends have gotten 16 years equivalenc for 2+@ degrees, But one of them had Bcoms + Msc Econ
Other had Bcom + Mcom.
I have BA + MCS..... looking for the same answer
Did you have luck finding that answer? If yes, please guide me too.....
I am sharing a thread that I started on the same subject, along some links I have
