Nafl fasting during exams
I've got my A level physics paper 1 tomorrow, and I'm not sure whether I should fast because of dhul hijjah or not.
If it was Ramadan there would be no question, but the fasts of dhul hijjah are not compulsory.
Despite that, there is still a highly emphasised reward of fasting during the first 9 days of dhul hijjah, so I am not sure if I should fast, especially because its an afternoon 2 hour exam, so I'll probably be hungry by then and I would have been revising all morning, so I may be low on energy?
I know a lot of people fasted during Ramadan back when it fell in the exam season, so I was hoping someone could let me know how difficult it was?
Or just general opinions or advice on what I should do?
