With 15 questions with four answers based on simple guesses, I have less than 0.0001 percent correct answers. 

First, LinkedIn doesn't let you copy and paste here, so I was forced to use Microsoft's tools against LinkedIn using the nefarious Windows Snipping Tool to quickly take a question and send it via WhatsApp to an accountant - this usually lost five to 15 seconds, which not bad.
