Increasing body weight strenght - how?

I want to join a Circus Training School in my hometown. I am very good at tumbling, but my strength is horrible.

The requirements are:

20 Deadhang Pull-Ups

20 Hanging Leg Raises

Climb a rope in L-Hang position

Press Handstand form P-Bars

Planche for 3 secs

I am a girl, I can do 3 Pull-Ups and 1 Leg-Raise. I have 1 year time to achieve these skills.

I am now wondering how I should start working for it. I go jogging 3 times a week for 45 minutes and have tumbling training 3 times a week for 2 hours. But we don't do strength.

I eat healthy, clean and try to get in a lot of protein.

Should I do a 1 hour workout of body weight exercises every day at home?

Or go to the gym 3 times a week for 2 hours? Will weight lifting help?

I have no idea and there is noone I can ask! I feel so lost with my dream. I want to work hard, I have all requirements, all I lack in is stregth - it so bad! Do you think I can achieve it? I have exactly 13 months to get there - then they close the application for 5 years before they start a new one.

Please help me, I really wanna do it!
