Mexico, about thirty-five young women were caught trying to cheat on their entrance exam to be teachers in schools in the Mexican state of Michoacán. They allegedly had the correct answers pattern for the paper painted on their nails. The whole admission process into teaching schools in Michoacán had been held under suspicion of fraud since the first stage of the exams.
On the last day of July, it said that several students had bought the answer for 15,000 or 25,000 pesos. Even though it was not officially proven, the claim was virtually confirmed by the astonishing test results in several Michoacán municipalities. According to local Mexican reports, 50 applicants who took the exam had answered all 100 questions correctly, while another 300 had scores of 99 and 90 correct answers. This was unusual, as in other municipalities the highest score was 71 correct answers.
In order to eliminate all suspicion of fraud, authorities decided to repeat the exam on August 21 and then managed to catch at least 35 women in the municipalities of Morelia and Arteaga trying to cheat with a very ingenious system.
A video posted by the Primera Plana Michoacan on their Facebook page shows a very similar technique had been used which they painted the 100 correct multiple-answer on their fingernails.

All of the cheater’s ar then were asked separated from the rest of the group and asked to either put on opaque gloves to completely conceal their hands, or at least cover their painted nails with sticky tapes instead of getting barred.
The coordinator of the test, Gabriel Santillán Mora, confirmed that all the 35 women had the exam color and dot pattern on their nails. Also, each nail had 10 dots of the same colors. It should be noted that the exam questions were answered by filling the options marked with circles on optical sheets, so it is clear that the dot pattern was some kind of system to how and in what order they should answer the paper.
