This was a required calculator for my circuits class in college. Once I understood the majority of the functions on this calculator I could fly through calculations very quickly. It is a very power calculator and well worth the money if you are doing lots of calculations. The multiple registers are great to store intermediate values which is EXTREMELY helpful with some longer calculations.

Awesome scientific calculator! Very clear display and does all the calculations that I put it through well. All in a cheap price as well. This was a great buy and I'd recommend it to any college student on a budget.

Works amazingly. Bought this as my previous one had the screen shatter somehow in my backpack. Feels great and the screen is bright. Would like some solar power somewhere but the battery on my last one lasted around 3 years before the screen... The protector definitely helps as i've dropped it and have it hit a sharp surface on the face of the calculator many times but had the cover on to shield it from most damage.

Exactly what I needed for stats. Make sure your professor knows how to use and teach how to use this calculator or else you're going to have to spend some time playing around with it.
