This is especially for students. Here at Birmingham University we've put up a blog for those who want to request prayers for exams. The blog is here.
So if you have exams - or anyone you know has some - just click on the date on the right when they have the exam (or essay deadline) and in the combox add your intention for prayer. These will be remembered at Mass and Adoration each day, and also be in the prayers of other Christian societies too.
