孩子有了一所学校offer,但还要坚持等心仪学校的转正。发了offer的学校的合同里写道:I acknowledge and understand that my obligation to pay tuition and fees for the full academic year is unconditional as of April 1, 2017 (or in the event I execute this Enrollment Agreement after April 1, 2017, upon school's acceptance of my executed Enrollment Agreement). 那是否意味着,我如果签了合同,且过了4月1号再申请放弃offer的话,是不是也要交全年的学费?谢谢!
