Any Proof she actually "attended"/ was "present"????
I am not sure about 1961, but In 1962 the Fall Quarter at the University of Washington did not begin until the last week of September or the first week in October. (I didn’t attend, but my friends did.) I registered for evening classes for the Fall of 1964 during the last week of September and I don’t think they began until Oct 1. It was not difficult to register for night school—and you could drop classes without a penalty until mid-November. I dropped Organic Chem when the curve kept dropping out below me. I did not receive a permanent student number until I registered for regular classes in the Fall of 1965. My point is that registering for night school did not imply any immediate time commitment. I had a full time job.
