I had a tutor I met once a week for 3 months. We studied one page, a page that listed all the letters in their tone groups plus the diacritic marks. She would give me homework of vocabulary words that I had to look up in a Thai-English dictionary which forced me to learn the alphabetical order. I would also practice writing them. We would work on pronunciation at our weekly sessions. It was the tones that were tough for me, thought I'd never get them because I just could not hear the difference.
