TI Revamp is spot on

TI Revamp is spot on
EDIT/UPDATE:If you are taking any math beyond pre-algebra or algebra 1 you will need at a minimum the TI-Nspire CX-CAS and NOT the TI-Nspire CX. The other version is better for algebra 2 and beyond. I typed in the command to extend a ploynomial and the TI-Nspire CX had a pop up that said, "try the TI-Nspire CX-CAS" It's a great calculator all the same, I really wish I had known it was not advanced enough when I bought it about 3 weeks ago. I have my second math exam tomorrow and will have to familiarize myself with the TI-Nspire CX-CAS tonight. Thanks to Amazon's same day shipping it's only a minor set back.Immediately worth it.Many years ago, I was loaned a TI 81/82/83 to use in school. I never bought one.It never occurred to me that a newer version would make that much of a difference. I thought, "I can use my phone for graphing and stuff or a computer program." I never gave much thought to a futuristic TI-Nspire graphing calculator.I had a scientific calculator and was mostly a C student in math, until now.Now I'm in college algebra at Thomas Edison State University and I saw my math score go from the 80% range to the 90%+ range. I became an A student with this calculator. Having the right tools for education make all the difference in the world.I absolutely recommend investing in your future with a good graphing calculator and for college students this is a must have.I was completely floored by the trackpad style cursor button!It was pretty easy to use. I haven't used a graphing calculator in 12-ish years, but I picked this one up and it was familiar enough that I could immediately graph and perform algebraic calculations.It came just in time, despite our Nor-easter storm. I used it today for my first college algebra test, graphing, functions, systems and all that fun stuff.I love that this calculator is the perfect blend of the classic TI calculators with some futuristic feeling features that make it a little more zazzy than the older non-backlit 8 bit pixelated clunky calcuators.This one is light and holds a charge and can work for a long time off a single charge. No more eating batteries the way the old ones did.It's also super light.I was nervous about the purchase at first but it is 100% worth it.
