I have done around 20 practice interviews for mathematical subjects for Oxbridge. If in the off chance you need somebody to help do this, feel free to reach out. (If yes, let me know and I will share my contact details with you via linkedin)
Regardless, good luck with this! Very useful for teenagers to get this advice which is otherwise not available.
What is the current funding status of AISC?
Which funding bodies have you asked for funding from and do you know why they are not funding this (assuming they chose not to fund this)? The funding options I know about are OpenPhil, EA Funds and Non Linear.
My understanding is you only just managed to get enough funding to run a budget version of AISC 10, so I presume that means you'll be looking for funding for AISC 11.
