Hi happyjo, I have the pleasure (?) of being able to study without child-sized distractions-except for my fur baby-which should mean less falling asleep. However, it doesn't! I am not even a "typical" student: I am 21, living with my partner, rarely go out, and commute to Uni. However, I am still knackered most of the time! Also about to embark on my 3rd year (it sounds as if you are-forgive me if I am wrong). I had every intention of pre-reading, but things seemed to get the better of me. Oh well, fingers crossed that if I come at it running I won't lose momentum!
Roll on graduation. Lots of luck for this year, and in this blissful 4 weeks before you return, start a new, cheap, hobby. Cardmaking, floristry, a language....Whatever you like!
