Maladaptive Daydreaming: where wild minds come to rest
I very recently took one. Honestly speaking in a 2-3 hour exam where you have to write longer essay type answers and stuff, I have not been able to stop myself from daydreaming. Mostly like how well will I do on this exam etc :-) but in ACT type tests, I always did well and did not daydream at all. Though preparing for them or doing timed tests at home have been a different story altogether. I would just not practice for them because I could not DD while doing them.
Shortly, I think don't worry too much about it. The fact that you will have at times less than a minute to answer a question will keep you focused. I think pressure situation does not allow you to do it.
@ BeStillMyHeart, story of my life :-)
I have blamed myself all my life, thinking I was lazy, a procrastinator etc. But it was always out of my hands. Hours turned into days, days into weeks and I would be either sitting at the same place or pacing. Pacing btw is such a common attribute in all of the people suffering from excessive day dreaming.
Best of luck for your exams.
