I would highly recommend Blue for any high school or college student struggling in their math class, and I wish I had known about him earlier. He is able to explain problems in ways that are easy to digest, especially for those who aren't naturally gifted at math. I also enjoyed working with him because he offers 1-on-1 tutoring, which is very helpful for the times I felt confused in my 300 something person lecture hall, as the professor obviously doesn't have the resources to give that much attention every single student in their class. Some important things to keep in mind before booking with him: he works with you over Google Meet, he charges $75 per session (each session is one hour long), and he only tutors up to Calc 1.
