I really like this program. My daughter was reading already but needed a little bit more practice and this program is excellent for her. We skipped book 1-23 and started book 24 and now she’s in book 34 in less than a month. Easy to read and the questions on every book is excellent addition. The questions is marker that she understands what’ she’s reading. I’m now starting my 4 year old- but it’s a slow start with him as his attention span is very short. We only do a little a time when he feels like doing it. Can’t force these little monkeys. Otherwise they won’t do well. I hesitated to buy this for a long time but I’m glad I finally got it and I wish I got it LONG TIME AGO.
