In the beginning Norae said she messed up her grades really bad in second year (because of the damn dude). So she probably took one semester off beginning third year in March (and summer break), then came back for the second half of the school year in Sep/Oct.
As of right now in the story's timeline, they already finished 3th year and waiting to come back as 4th year after winter break.
So when Sung Pyo asked if she's 4th year now its correct.
(It makes sense that they had the MT trip in the 2nd half of the school year when all students were familiar with each other already)
