"She yells math into my brain", "She is bipolar, screams at student and smiles to parents", "the year-end award toys were pathetic".... You can hear all these from your kids if they go to Ms. Tsai. But guess what, by the end of the day, their math improves, and they would all have to thank Ms. Tsai for giving them 10 pages of worksheet to do every week. Don't forget the short test everyweek, and worksheets during summer holiday.
There are other Math tutoring schools in Plano. Most of them are good. But my kids went to Ms. Tsai since kindergarten and now they almost finish middle school. Her class size is above average, but her fee is very reasonable. There is just not enough math homework in school. Ms. Tsai's material is a good fit to supplement the regular school work.
I read another review that she made kids cried.... I believe everything she said really happened. She made my kid cried too when he was 3rd grade, because he was not paying attention in class, not finishing work, etc. I think it was a good lesson for my kid and he deserved it.
In short, this is a great place to learn math. Don't expect to be pampered.
