We're also finding that IB is not very accommodating of accelerations. DD is interested in a lot of the program, but will have to jump through a lot of hoops to deal with timing of courses and exams.

We spent quite a bit of time looking into the benefits of an IB diploma vs just a bunch of IB classes, and there are few reasons we can identify to worry about the full diploma. The plan at the moment (10th grade), is to take the SL and HL classes when she is ready for the classes, and let the school figure out if they'll make the diploma work for her. She's taking a HL IB class this year as a sophomore, much to the IB coordinator's consternation. So be it.
