Excellent Lesson! Though this was the first episode of Gary sir's lesson, he taught program on equation of straight lines, which is very much useful to me. As this topic has always been burdensome on me since I was f3, Gary Sir helps me tackle the misunderstanding throughout these lessons and I am able to do questions more confidently now and in a high accuracy due to the help with his programming. Tbh even you are very skilled at Mathematics, I strongly advice you to take the lesson, as at least you can take his programming home. They are awesome!
