If you have filed your application under FSW there are two different factors to keep in mind for the eligibility.
The CRS; and
MEC
For the CRS you get highest points for 3+ years of work ex.
For MEC (FSW) you get max points for 6+ years of work ex.
You have to meet the CRS and MEC to qualify -

As regards your primary NOC, you have to have at least one full year of work ex to qualify under FSW. You can combine different NOCs to get those points. However, when deciding you primary NOC, you can pick anyone, as long as you have one full year of work ex in that specific NOC.
The status updates such as IP1, IP2 and NA are just indicative of progress in your application and based on speculation. To be sure if you have cleared "passed" eligibility the only sure shot way is through GCMS notes.
