What should I study prior to attending Air Assault School?

I currently have orders to PCS and hopefully I will be leaving next month. I am assuming I will have a shot to go to air assault just like must of the people who is stationed there. Any advices of what should I Study/trained before going? Also, I am interested in doing combatives but unfortunately my losing unit is not doing combatives any more fort COVID related/ “people can get injured” type of bullshit. Do they have the same politics over there as well? No idea ID my MOS is relevant but just in case I am 11B
