Summary: THE ONLY ISSUE I HAVE WITH THIS PRODUCT IS THE LACK OF DETAILED INSTRUCTIONS. THIS CALCULATOR WAS BOUGHT FOR MY DAUGHTER'S GRAPHING ASSIGNMENTS FROM HER MATH CLASS AND I ENDED UP HAVING TO PURCHASE A NEW CALCULATOR BECAUSE WE CAN'T FIGURE OUT HOW TO UTILIZE THIS ONE. SO ANNOYING.
Summary: This calculator is all you need (and then some), for the SAT Tst. It is not quite strong enough for the SAT Suject Tsts Math 1 & 2, but it can be used for those also. It is more than good enough for the regular SAT Resoning Test Math Section.
A GOOD CALCULATOR FOR THE PRICE(IT IS NOT A TI-83)

Summary: First I would like to say that this is actually a better calculator than a lot of people have given it credit for. If you are expecting this machine to do everything the TI-83 does, you will be upset because it does not. Not by a long shot. The manufacturers are not being totally honest when they claim it can replace a TI-83. If they had not put this untruthful claim on the box in the first place, maybe the calculator would receive more higher ratings than it has.
