Swimming times for a new swimmer ?

I am 16 and I have never done competitive swimming. I did my first time after 4 days of swimming and training. The time was 36 in 50 m freestyle . Then two days later I did my second time and that was 33 seconds in 50 m freestyle. Is this okay for a begginner and if I train this whole summer will I be able to reach the times I need? Thank you and I will take any constructive criticism
