If you are gonna do a lot of reading yes, at durham in chem to not get kicked out you have to go to labs and tutorials but lectures are optional.
It's possible to pass uf you skip lectures, but you need to read stuff in your own time.
Lectures are the foundations upon which a course is based. They introduce you to a subject area or concept and then expect you to build on that knowledge through reading and research.
They are not vital and in most universities are not compulsory. However I would tend to think that frequent non-attenders would be at a disadvantage. Having said that I know this to be true because when we have essays to do they are all frantically ringing their friends asking for help!
