ooh same, I’m also hoping to use my TO for ILR next year. I mean, if you haven’t already contacted Ian by now, the rule of thumb according to him is to have the same grades as semester 1. However, there are exceptions based on how you have performed, what reasons given if your grades do drop, and the strength of your overall record, along with other factors. If you are unsure, I would contact him about this specific question, he was able to put me at ease and provide me with a comprehensive answer.
