Keeps me concentrating, especially if i make myself open and recast the circle everytime i step in and out- i just end up not bothering to leave and really focusing on my study instead! Praying can also make you feel a lot more ontop of your work if you feel you're having trouble with coping, or if you just unconfident before going into the exam. Even if you don't believe in a deity, there's evidence that praying is metally good for you because it allows you to share your feelings instead of bottling them up inside of you, or sharing them with someone else when you don't really want to spill!
well thats all i can think of at the minute, but if i think of anything else, i'll be sure to post it. Please reply if you found this helpful, or you'd like to share how you revise- let's all try to help each other as much as we can, okay? Wishing you all the best for your exams x x x
