How can I stop being so forgetful?

I go home walk my dog, do homework and chill then fall asleep normally, then I forget stuff for school.

Lately my physical education class days have changed so I forgot my PE kit and shoes twice but got excused the first time and had to wear spare top and shorts the second time.

Now I left my PE kit and shoes which was in a bag on a train and it sadly never got handed in.

So now the school have insisted they keep clean top and shorts at school for me and my mum has agreed.

I guess it's working as I have not missed PE class anymore but I wish I could be more organised.

Any tips?
