Perfect for my Accounting Finals

I bought this specifically for my CPA prep courses. The natural display makes entering complex fractions so much easier than my old calculator. It's allowed in all my practice exams which was a huge relief.

Exam compliant and reliable

Verified with my proctor that this model is allowed for the FE exam. It works perfectly, boots up instantly, and the screen is very clear even in low light thanks to the contrast settings.

Engineering Student Approved

Using this for my civil engineering certification exam preparation. It handles matrix operations and trigonometry effortlessly. The solar backup is great so I never worry about batteries dying during a long study session.

Great value, sturdy build

Very solid construction. I dropped it once on concrete and it didn't even scratch. The keys have a nice tactile feel. Only giving 4 stars because the manual could be more detailed for advanced statistics functions.

Best upgrade from high school calc

The dual power source is reliable. I love that it shows the equation and the result on separate lines. Makes checking work for calculus problems much faster. Highly recommend for college entrance exams.

Good for the price point

Does everything I need for my graduate statistics class. The buttons are responsive and not too clicky. It took me a day to get used to the menu system, but now it's second nature.
