Typically everyone starts from the first semester of the program. Admission to a higher semester is only possible if there would be free places (which in the past has been happening rarely). If there are free places and an application for the summer term is opening, you need to be able to show/argue that you have taken courses that cover the teaching content of the first semester of the MCNB. As this will be challenging and an admission rather unlikely, we advise applying for the winter term and discourage applying for the 'higher semester' in the summer term.
