'Please provide any additional information that you think is relevant.'
What type of thing do we think is actually relevant...
It really depends what you've managed to get out in the rest of the form, and what else you might have to say.
For example I would say "I am able to take SQE2 at the next sitting, with or without a preparation course, and would be able to start before 2027, if convenient."
Academic achievements that are not captured elsewhere would also be relevant. E.g., perhaps if you were awarded a scholarship.
