Just a really quick question.... We have used IXL Math for the past three years...love it and have seen our test scores really improve. This year, though, we are experiencing problems when using it. It often freezes up when the students submit their answers, and even when working, it seems to take twice as long as before to move between problems. Was wondering if anyone else who uses it has noticed a difference? I know they have changed their format somewhat, so we are wondering if it something that IXL needs to be made aware of, or if the problem lies in our own network system? Thanks for any input you can give us.
