    This is a great program for study abroad in junior year. The Hungarians are world-champions at combinatorics. (The College does not have a language requirement in effect for this program.) Many, many Middlebury students have gone to the program and loved it. Application dates are twice a year - check it out!

    For your homework you will need to use LaTeX, a tool for typesetting mathematics. The use of Overleaf has gained widespread popularity - it is a "collaborative, online LaTeX editor that anyone can use." Or you can proceed the old-fashioned way...Have you got a Mac? Get TexShop here. Have you got a PC? MikTeX is here and TexnicCenter is here.

    To give you an idea of exams from previous times I taught the course.
