Mr. Reini is teacher # 4. That is my 99.9% guess. He's teaching Algebra 2. Last year when I searched teachers out I did a search for him online when they posted his name b/c I couldn't find any reviews at all and he came up on the community college reviews and he got great reviews there and we can attest now that we have had him for pre-Algebra. He's humorous, entertaining and yet teaching what they need to know with a great skill. My daughter doesn't love math but loves the class because of him. Now if I could get her to just correct her errors that would be great! But she gets the concepts. We have done CC for 3 years and it has really helped with my kids writing for sure. This is our last year of it, but they are finishing Challenge 1 and we are ready to just do classes.
