 Now most students are accustomed to using practice questions very traditional way which is to do the questions, see if you got it right or wrong, read the explanation, move to the next one. That doesn't really help your confidence level if you can't see the answer. So threshold training using practice questions is basically doing a random block of questions, maybe five to ten at a time if you're struggling and not knowing if you got it right or wrong. And just like running, instead of your lactate you'll find that your anxiety starts to peak at a different amount of questions of uncertainty whether you got it right or wrong. For me it may be doing ten questions in a row and not sure how many of those I got correct. For you it may be five or fifteen. Do that amount, set those sessions up and try to do it with a timer as if it was a real test.
