Will there be an option to manually add PrepTest scores and lesson progress? It feels like an oversight to make the new site completely incompatible with the old, given that you are advertising the improvements as significant for performance.

Do you think that "given that" could also function as a premise indicator? For example, you could say: "Not all mammals are suitable as pets, given that tigers are aggressive and can injure people."
