A tech tool that really helped me out this year was "Khan Academy". Math this year was really hard for me and I couldn't understand some concepts or we didn't have enough time to fully go over it in class. Khan Academy  gave me access to all kinds of math videos and practice problems for me to better understand a math concept I struggled with. Without Kahn I wouldn't have have averaged an B+ in math so I am so thankful I had access to this website.
