I ran the 75 m in 8.00 seconds is that any good?

As the question says i ran 75m in 8 seconds and then my second attampt straight after was 8:04, i then was the was the anchor for the relay and did 100m in 10:36 just to say i am only 14 and i was wandering if this is good enough to join the schools track team as well as a proper team ?
