Realistic expectations 6 months from now

I started my training exercising around April. Started training for mil a few weeks ago. Here's where I'm at now:

Current 1 mile time: 8:00 (today’s PR)

Consecutive push up max: 40

Consecutive pull ups: 10 (today’s PR)

Consecutive sit ups: 40

My swimming fucking sucks because I’m still learning the sidestroke and I’m stiff as a board/keep huffing water. I don’t know what my swim time is.

I’ve started doing 200 push ups throughout the day every other week day and lots of cycling training to improve cardio/endurance without impact. Been doing pull ups just as I can, I’m getting a pull up bar here in a few days to do them intermittently throughout the day. I’m 21, 165lbs 5’9”. I’m visually in good shape/muscular, but need better cardio numbers.

I think I could realistically be at 80 push ups/sit ups, 20 pull ups in 6 months from now, but cardio wise where (estimated) could I be? If it helps, my cardio in July/August was 10:55 1 mile, so I've actually made pretty good progress.

I skimmed some of the sidebar exercise routines and I'm setting those up, was just wondering about sub opinions.
