If you are taking summer classes at Michigan Tech then it is treated just like any other semester, regardless of whether or not you are taking a full load of classes. Doing well in your summer classes can bring you off of academic probation. Doing poorly in your summer classes can put you on academic probation or count towards an additional semester of probation if you are already on probation. Go to the Dean of Students webpage for more information on the academic probation policy.
If you are taking summer classes at a different school then it will not affect your academic standing at Michigan Tech.
