I have basketball Tryouts tomorrow, I've never played on a school team before, can I make it?

I'm a junior at a 4a highschool, and our basketball team is mediocre. I used to play basketball at the recreation center every friday for 3 -4 hours, but the last few weeks ( 3 - 4 weeks) I haven't been able to go to the Reccreation Center. This year I was debating to be in basketball for a long time, and I finally decided I want to be in it, however today during the school's announcements I learned that the basketball tryouts are tomorrow. I am small, 115 pounds, and 5foot 7 inches and pretty weak but I feel like I can shoot better than most of the people on our team, and I dribble pretty well. Do you think I can make the JV or V team ( the only teams I can make it to as a junior) if I try my hardest at the try outs tomorrow? Also, I'm embarrased about working out with the team if i do make it, because I'm the smallest and weakest one. I'm weaker than most freshman, but I can predict that once I work out routinely I'll have a six pack, because I have like no fat but no muscle either. Do you think I should go to the basketball tryouts, and do you think I can make it?
