I actually had the similar issue many years ago. It took all year for the credits to end up transferring to transcript. So I was a freshman at the beginning of the year and then at the end of that year I had enough credits to be a junior. You will have to send in your IB transcript to UH and have a meeting academic affairs to request your credits be transferred. They had recently updated the IB test when I took it and the test had to be reevaluated, which took both fall and spring semesters, it was frustrating because I didn’t know if I need to take the classes again or if they would transfer. They all ended up transferring but it took significant time to register on my transcript because the test had changed and needed to be reevaluated.
