He seems like a really cool guy honestly, but he's probably one of the worst teachers I've ever had. It doesn't matter how hard you try to get along with him, he's completely unreasonable. Expects immaculate work on things he doesn't explain too well. Don't expect any leniency from him if you're male. He rants too long about hard work and success during lessons. He's the type of person who judges you on the first day and treats you accordingly. Would never recommend his class.

Everyone keeps complaining about Mr. Lai, however what people dont understand is how easy his class is. although he is a but picky about how you do the math work, he actually does explain how to do the problems. Most of his quizzes are really easy and most his test questions are online. Trust me hes an easy teacher as long as your willing to put in some work.
P.S. You always want to be a "high acheiver" LOL

Good points
-Lectures slowly, clearly, and logically
He explained the Ideal Gas Law from a logical perspective instead of having students just memorize "this increases when that decreases."
Bad points
-favors "high-achieving" students
-unreasonable rules (ex. you can't lean your head on the desk)
All in all, he's not the best teacher at keppel but also not the worst. If I was forced to retake chemistry in Keppel, I wouldn't mind retaking his class. All that matters is that he teaches.

He is a very good teacher. He is very forgiving. When I don't understand something he takes the time to teach me.

You're gonna have to teach yourself to get an A in this class. Also, he expects you to have a computer with Internet at home, or you'll be making a lot of trips to the library just to get assignments.

He just rants about random stuff. His study guides don't make sense and he just tells you to look on his webpage everyday. Nothing in his lectures pertains to chemistry at all.

If you talk to him enough, he'll start throwing you a bone(extra credit)His class was a bit hard, but to me, chemistry is usually hard. If the class overall does bad, he'll start a lot of extra credit
