How many noc codes should be in my ee profile (2171, 2147)

[arasola2000]

HI,
My current ee profile score is 421 so i am looking for ways to boost. I have started french training.

However i used just one noc code in my profile 2171. However i have previous experience with 2147.

Is it advisable to have more than one noc code in your profile?

Hoping this will make me eligible for OINP.

Thanks in advance
