hi, I am a first year engineering student and i was wondering should i go to my classes or the event in frosh week. thanks in advance

University, just like life is all about making decisions. If I were you, I would go to my classes and attend whatever activities I can outside of class time. Others would just attend all of the activities and skip classes.

I didn't attend frosh week. It's just a matter of preference.

Does anyone have more info on the Gulliver's lake Engineering event? I cant find anything online except for when it starts. Any info on buses and the likes?

You SHOULD go. Well, it's all up to you. But in the first classes, they give introductions, give a nice break down of the course, and tell you what exactly you need for the course (textbook, lab wise)

Frosh. You won't miss much

If you're going for the social aspect (i.e to make friends), then class should be your priority instead of frosh. You're going to make friends regardless.
