Where are good online tutors?
Sirop Sar commented
You can find good online tutors on https://www.getutor.com.hk/. I was using the services of a tutor from that website when I was in high school. I was having problems with chemistry, and I was sure that if I didn't find a tutor, I wouldn't pass the final exam. We organized online lessons every Saturday for two hours, and he explained Chemistry from the beginning to me. I liked that I started to love it, and finally, I got a good mark on the exam, and I am very grateful for the help of my tutor.
