    I usually tend to run out of time (in my physics paper) as a result i keep the multiple choice questions to the end. Let's say I have 2 mins left and 10 multiple choice questions. Statistically what would be the best option for me to do? i.e chose all of the same option (all A) or randomly or what?

    I'm not really that good at maths but I think no matter what answer you choose for each individual question the chance that it will be right is still 1/4 so you might as well choose all a or random ones.

    The answers for multiple choice are totally random and computer generated by exam boards as it is a requirement of Ofqual. For yourself to get the most amount of marks in that 2 minutes just answer all the questions as there is no magic key to getting the most amount of marks. Exams have been purposefully designed that to avoid any form of bias for any specific option (a, b, c or d for example)

    It's because, in the past by me guessing D for all options I usually got 4/10 and sometimes 5/10
    but when i guess random i get 2/10 and sometimes 1
    So i thought there was some kind of logic or mathematical relationship between guessing the same one and guessing different ones

    Try to eliminate any definitely wrong options. Even if you only know one choice is wrong, it goes down to a 1 in 3 chance of getting the right answer.

    You might as well tick all As, or all Bs, or any random combination, you have no way of knowing any given one is more likely than any other given one
