Question regarding the Total Years of Schooling (Research)

Hello. I have a question if anyone could answer me.

I'm a bit confused on what to write for the part regarding the total years of schooling attended as of April 1, 2027, which is under the Academic Record.

By that time, I would already be in my second semester of my Master's program.

I have already completed the 12 years of Primary, Lower Secondary and Upper Secondary Education, and my undergraduate was 3 years. Those, together with the first year of my Master's program, would be 16.

My question is, do I count the first semester of the second year? If yes, then do I write 16.5 or...?

Also, I have previously been a Japanese Studies Student which is one year. Do I have to count that too?

Thank you!
