[header] How to adjust to school as a transfer student [title] Decide when to transfer. [step] If you're able to determine when you transfer schools, try to begin classes at the start of the school year. This way, everyone is adjusting to the new school year and classes at the same time you are. <sep> (A) [substeps] You can take early transfer classes for discussion and class participation, or you can let your teachers know when you transfer as soon as possible. [title] Prepare to make several changes to your school, if at all possible. (B) [substeps] Many end-of-school transfers can happen so that students can move to different schools. Most other transfers (make sure you're close to your school, if possible) occur about six months after you were admitted. (C) [substeps] In some cases, you will need to wait several months before transferring students from the same school into the new school. Others, you may need to wait or step back and wait a year or so to switch schools. (D) If you can't start at the beginning of the year, at least try to start when a new term or period begins. [substeps] If you have no control over when you start and you have to start during the school year, try to meet with your instructors.
