It’s quite a dangerous practice to require someone to get a skill for a specific date. Gymnasts should be aiming to get skills, when they are physically ready, not for a date/event etc.
Practicing aerials at home is also quite dangerous. Aerials place a lot of pressure on knees and ankles, because you are landing with all your body weight on one leg, and when learning we often land at a funny angle. It is quite easy to dislocate your knee, with an incorrect landing. Once you dislocate your knee once, your are generally plagued with life long knee problems.
I assume you are not attending classes now, as most of the world is not. But you can prepare yourself to return and better at aerials by working on your flexibility, especially all your splits and doing activities for leg strength and power.
