Ok I need answers on summoning spirits

I called Lucifer this afternoon and asked him to give me the knowledge to pass it with a perfect score. I didnt pass it with a perfect score but i did WAYYYYYYYY better than i thought i would. I think this is because of him im not so sure. I called him by holding the sigil on my left hand and says his enn. I thing i felt something im not so sure. Did Lucifer help me or nothing strange happened. I didnt see him but after a while after i called him i felt unsually worried, not the testing kind but EXTREMELY worried. Did my evocation work?

Is that a result? Yes.
Should that be kept in mind for further Workings with him? Yes.

So he did help me?
