Ms. Pim must be new but Ms. Oh is great... She was never fazed at even my most ridiculous questions.
Are you just using the Becker books Git? I had 3 kids books... Yellow, Blue and Pink I think. I used to make a point of not going home as I'd switch on TV, put my feet up and procrastinate. I'd go to Irish Clock, Richmond Steak House or Fuzzy Ken's to do my homework...

One day in the Irish Clock lovely On (no longer there) saw what I was doing, called Mali over and almost fell around laughing at my efforts in writing Thai like a 5 year-old.
Thai characters are so intricate but practice makes perfect.
Keep at it young jedi... Your efforts will be worth it in the end...
