@Lady_Eva But I love chocolate and bacon!

But listen to the Lady, @joherb_theo. I use to combine some magickal methods, but I use them on different steps of the whole process.
About the exam, Vapula has the power to enable a period of practice that makes you an expert in any area of study. Call him and ask help to study.
Paimon can manipulate some minds in your favor. Orias can work on âjudgesâ mind to perceive you worthy and skilled, so you can win a competition (in that case, your scholarship). Auns can be helpful by improving your creativity in writing if you need to. If youâre going to an interview, Ose can make you look more skilled or intelligent than you are, so you can make a good impression.
All that said, you have to take those informations and work by yourself. Iâm being vague on purpose here, because you need to look to this and make your plan. After you have it, and had studied a lot, you can work your way into these magick operations, opening your road to success.
And also, do your best. To put things to work you have to make your own effort in the physical realm. In that case, eat those books on your breakfest. And good luck, wish you the best.
