Listing IB courses twice

On the self-reported course work part of the application, do I list IB courses twice? I’m taking the full IB diploma, so each IB class is two years long. Does this mean I should list IB Bio, Physics, Math, etc. for both 11th and 12th grade? If I do that, I don’t have room to fit all of my earlier classes, so would I put those in the optional section at the end of part 2?

It doesn’t matter. Put your classes down any which way. What doesn’t fit in one section put in the optional section.

If you don’t have room, I would put "two year sequence ") after them. But I would make sure it is clear that you took 2 years of each of those.
