Summer is here

Hopefully, I have finished my university exams. Now, I have a lot of time to spend learning English and earn some money.
I'm going to try to teach children how to play the drums to children this summer, I have a beautiful drum set that I used when I was in a band, (OR, when I used to be in a band) and now is the time to take advantage of it.

Dont forget to use a capital ''I""    I was in a band.  I am tall. etc.
