I have twin granddaughters, born all of 3 months too so, in 1993 (Preemies-one 2.3 lbs, one 2.2 lbs). Fortunately, they have very limited disablities. They have exceeded where the doctor's did not think they would. The smaller of the two had a very difficult time in school with math and science making her about 6 to 7 months behind the average child, until I purchased the iQuest 6th-8th Grade Math Cartridge and the iQuest 6th-8th Grade Science Cartridge. I have seen some improvement in her school work as she uses her iQuest while doing her homework. She loves it. They are now going to the 9th grade. I would like to see the iQuest continued from the 9th on. I believe this would benefit them greatly. I am waiting to purchase the Social Studies Cartridge as soon as it is available.
