### Rushstudy - The vocabulary test app that will help you study with the help of mathematical models

A few days ago I read the book Predictive Analytics. A chapter in the book was about the computer machine that won Jeopardy! One of the humans who competed against the machine, Roger Craig, used a special way to prepare himself. This is an excerpt from the book:
...To prepare for his appearance in the show, which he's craved since age 12, Roger did for Jeopardy! what had never been done before. He Moneyballed it.
Roger optimized his study time with prediction. As a mere mortal, he faced a limited number of hours per day to study. He rigged his computer with Jeopardy! data. An expert in predictive modeling, he developed a system to learn from his performance practicing Jeopardy! questions so that it could serve up questions he was likely to miss in order to efficiently focus his practice time on the topics where he needed it the most.
This bolstered the brainiac for a breakout. On Jeopardy!, Roger set the all-time record for a single-game win of \$77,000 and continued on, winning more than \$230,000 during a seven-day run that placed him as the third-highest winning contestant (regular season) to date.
This sounded like a good idea, so I decided to develop a similar system for everyone to use. The result is "Rushstudy - The vocabulary test app that will help you study with the help of mathematical models." This is a screenshot:

You can upload your own files, but if you just want to test it, I've already loaded it with the periodic system. It will keep track of the questions that you answer wrong, and the probability to get those questions in the future will be higher. I've also added a chart so you can keep track of your learning process. This is not the final version, so I will improve it in the future.

Looks interesting? You can test it here: Rushstudy - The vocabulary test app that will help you study with the help of mathematical models
