does it matter if i have the tutorial before the core for this course. it would be in the same day (on mon.) about 2 hours before the actual core. is this alright or is it better to leave it on different days, (right now core is on mon. and tutorial is on thurs)?

Nope its fine! Thats exactly what I had last year. The core for 1XX3 is a live lecture, and the tutorial every week only covers the material from the web modules

thanks a lot!
