I’m very appreciated that you always consider your students but 3 questions were not consistency such as

Where have you been?..... (in the past)

Who do you go with ?..... (at the present)

Who did you go with ?..... Should be!

What can you see?...... (at the present)

What have you seen?...... Should be!

I am concerned students might misunderstand about sentence structure.So I will keep my fingers crossed for you.

Please feel free to contact me every time at your convenience.

Your Faithfully
