here is how this timer works. start the program, then type in the amount of minutes you want then click the check-mark, then it will ask you if you want to start the timer. type in yes if you want to start it then click the check-mark.
One word: homework. I have tested it out and it works. it works if you are in a different site. it's very helpful and I guarantee it will not only help you but the community of scratch. : )
