孩子已在美国读美高10年级，想10申10，请问重读10年级对申请大学有什么不好的影响？需要和大学解释留级原因吗？_留学问答

There are generally 2 good reasons to repeat a year. One is health. But you need to have sufficient documentations from doctors. The other reason is academics. Your child should only repeat a year with the recommendation from the school. Your child will need to explain in detail when he/she is applying to college.。
