Can I make my high schools softball team?

Hi, Ive been playing softball for 6 years on my local rec team. My parents would never let me go on a travel team cause they didnt have time to take me places. I think im pretty good but I have a feeling the girls on the travel teams are better and will be trying out too. I guess i'm not very good at trying out for things cause I already tried out for cheer, basketball, and the flag team and I didnt make any. My school is one of the best at athletics and win almost all conferences (just to show that people are very good at sports at my school). Do you think i have what it takes and what should I do to improve myself?
