Auditions tomorrow and cad module

Having a cad module tomorrow, I did not print the notes out as the pdf was too outdated it seems. First ever cad lesson only anyways,should be okay to not print it.

Also after school tomorrow I am having voices auditions. I hopefully I will be accepted, only problem is that my voice can crack up sometimes. Another is that my voice is a little to deep sometimes, I do not know how to "deactivate" it sometimes. 

Maybe there are techniques to overcome this idk.

Anyways I gonna give it a shot. Sleeping early for better concentration tomorrow.
