Questions about Islamic Prayer??

You may learn Duas when you're menstruating. The obligatory prayers (with the bowing and prostrating) you may not. For that you have to be in a state of ritual purity and that's impossible while bleeding. Prayers you miss during that time are forgiven in Islam. If the Muslim students are going to congregate on Fridays, if they can't attend a mosque then that's Jumu'ah. They probably lead a discussion or "lecture" in there at the time. It's an obligation for men to do that ever Friday, but it's not required for women. I'm sure if you wanted to go to learn, you would be most welcome. :-)
