Amazon Whisperer

The way that my company would generate revenue is buy partnering with Universities, and having the Universities pay a fee for these proctoring services. Much like ProctorU, a student would be able to arrange a proctored test about a week in advance, free of charge, but if the student reschedules the appointment within 48 hours, the student would have to pay a small fee. My company is a service-based company, so I can't really think of any product that these students would want on top of the opportunity to take an in-person proctored test versus an online test through ProctorU. A device that I think would be useful though, is a calculator that is a mixture of both a graphing calculator, and a financial calculator. As a business major, it is pretty annoying to have to keep track of both calculators and see which one I can use for a specific problem. I think a calculator that has the features of both, could be extremely useful. I can't find a calculator that encompasses both features on Amazon, but they have each individual calculator. The reviews of the graphing calculator, specifically the TI 84 +, are extremely positive and has an overall 4.5/5 star rating. The reviews say that is is extremely easy to use, and very convenient. Reviews on the financial calculator are not as positive. The Texas Instruments BA II + financial calculator, has a 4/5 star rating. The reviews say that it is not as intuitive to use as regular calculators, and people wish that it could do a little more. It is very intricate and use must use so many buttons to perform the simplest calculations. I would combine both the financial and graphing calculators into one calculator.
