Two semesters are offered each year; each semester comprises 14 weeks of teaching and one week of examinations. The eight-week summer program begins mid June and ends mid August. There is a brief orientation program at the beginning of each term. The farewell party for each term will typically be on Thursday.
A student may participate in either semester or in two consecutive semesters. The academic program always begins on a Monday and an orientation session for new students is held on Friday of the preceding week.
The Spring 2019 semester includes a one-week break, April 15-22, 2019, usually before the Easter weekend. The Fall 2019 semester breaks are 10/19-23; 11/1; and 11/28/18-11/29/19 during Thanksgiving. There are no classes on March 15, May 1, Whit (or Pentacost), August 20, October 23, November 1, and Thanksgiving. The office in Budapest will be closed on these holidays.
GRE Testing will be October 26, 2019 for the fall semester and April 4, 2020 for the Spring Semester.
The Babilon Language School offers a 2-week intensive language course (non credit) in Hungarian about two weeks prior to the beginning of the fall and spring semester; a shorter session for the summer semester. This is an optional choice, not included in the Budapest Semesters in Mathematics Program tuition. The cost of the optional intensive language class is around $350.00 payable by the annual tuition deadline for fall and spring and the cost will increase to $440.00 after the deadline and be paid after arrival in Budapest. Summer 2018 will be $200 by the May 1 deadline payable to BSM, and $250 after that date and payable to the Babilon Language School upon arrival in Budapest.
