Please note that all of the resources that I make are actually for myself. Of course, please do feel free to use any of my resources if you wish but I kindly request that you do not show hate as these resources are mine and I have spent my time making them to help me with my tests. I am aware of my spelling mistakes but like I said, I made these resources for myself. However, you all may use them if you would like to but if not, please leave. There is no need for hate.
