DD has just started a STEM undergrad course at Oxford. Its about 5 hours away from home and she has settled in well. But a lot of recent conversation is about how she misses lectures for various reasons such as some of the lectures being really boring or there was a more exciting lecture next door on philosophy/architecture/neurology/maths. She seems to be coping ok with the work load (its only week 3) but says she does the minimum to get by. She really enjoys socialising which often means she goes to bed really late- and is sometimes too tired to go to lectures the next morning. But apparently she can get by at tutorials by doing the readings/lab work etc on her own. Its not too hard and there are plenty of resources to help. She doesn't take alcohol (hates the stuff) or any substances. Socialising is just chatting away over tea or coffee or organising events, etc.
I feel quite alarmed at this metamorphosis from diligence at school to being much less so at university. I have never really overseen her study schedule while she was at home as she was so self-motivated. Should I say something? Is this how students usually are? I worry that taking it so easy at the start only promises overwhelm and tears closer to exams.
