Re: grammar points per lesson - help needed!
Welcome to he forum, Chac Mool.
I assume that you want to be appointed for what you are. If you think that teaching these two points (if indeed they are two separate points) in one lesson is a good idea, then go ahead.
Think how frustrated you would be if you taught what somebody else thought was right and failed to get the job. And, if you did get the job, you would be working in some ways under a deception - you would have got it by teaching something you didn't believe in.
