Hello,
I filled in the information now.
Seemingly there's no direct option of adding "Two or more certificates" in the Education level drop down, while filling in the express entry profile.
That option is only shown if you calculate score using CRS calculator.
The way I updated it -
1. First education level :
My degree - Added bachelor's
As per WES - Added bachelor's
2. Second education level :
My degree - MBA (Master's)
As per WES - Selected "1 yr program at university" option
The portal itself considered it as "Two or more certificates" and assigned me the marks for the same.
