I don't recommend

The school flyer on OLSAT test claimed we can’t prepare our children for the test. My child didn’t score high enough on the OLSAT the first year he tried, so couldn’t get in the GATE program. When I found out about your Building Thinking Skills® series, I got them and started several pages everyday over the summer. We briefly reviewed it right before the test, and he scored 98th percentile, making into the GATE program! Now I tell other parents, contrary to the flyer, we CAN prepare our children for the OLSAT test. Thank you!!!
