Newbie seeking points! 17 minutes, 17 questions (I wrote 15 questions, but two of them had two sub-questions), one minute time limit per question, webcam on, no calculators allowed. I've written down everything I can remember. Mostly calculations. Some I can still recall: Calculate the area of a triangle given three coordinates (this is easy). Calculate the length of a segment of a function (but I was too lazy to calculate and just estimated it; it seems like a proper calculation would require integration and would be impossible to complete). Calculate the percentage of prime numbers ending in 7. Calculate the percentage of people with 7 in their name (I just estimated it randomly; the key point is that it didn't even give the year the statistics started, only the age). Calculate how many more times you would need to toss an unfair coin if heads were higher than tails. Another coin-related question I forgot. Three questions related to six-sided dice, all calculating expected values. Calculate the value of the next term given the first term and the formula (this is easy). Calculate a number raised to the power of 0, a logarithm, a number squared, a number multiplied by a number, and divided by a number (I didn't even finish any of these). (I just randomly guessed and it was really frustrating!) There were so many questions like this, I think five or six. The further I went, the more frustrated I became. Seeing a bunch of questions that timed out and failed to submit, scrolling down for ages only to find I had 50-odd seconds left, reading the question and only having 20-odd seconds left, and guessing an answer based on gut feeling and then rushing to submit with 5 seconds left for fear of failing—after submitting, the more I thought about it, the more ridiculous my guess seemed. Is it even possible for a normal person to finish these without a calculator? How did they prepare? Maybe I haven't practiced enough questions, mainly because I don't have enough points to even see any online assessments on this forum. Anyway, I'm probably failing. Newbie asking for points!!!
