# Getting Help

Every now and again, we all need help. Below you will find various resources for getting help. The best way to get help is to use my office hours: that help is very personalized and can be the fastest way to overcome a challenge.

My math notes can also be helpful if you missed a class or a friend, parent/guardian or tutor needs to know what we covered in class.

Academic coaching is also an option for those who might want occasional or more regular help. There are also some online resources you could use too.

If there are other resources that you think might be useful to list here, please let me know.
