I'm still undergraduate, have 2 years to graduate but i don't like my major so much and my college. i go twice a week. i don't attend lectures too much because professors and the contents are so weak and doesn't based on understanding just on final exams and i don't like it. i started to learn from Youtube and other websites but the GPA is not good is about 2.3 so my wish and hope is to do master abroad as Europe (Sweden or other country) to live there and work better than middle east. So it can be or not ?! is it possible ?! i don't search for scholarship.. i can pay for studying but not much from working there but at least understand what i really study not just rules and put them in a paper to get full mark..
Yes, it does matter.
Slightly longer answer:
The GPA is one of the few ways universities can use to assess someone's academic abilities. There are a lot of flaws with the system but there aren't many alternatives. Presenting the courses and grades automatically indicates your (alleged) proficiency in the material. If you think your classes suck and you learn better outside of class, you should be doing the work in addition to your schoolwork - not instead.
In addition, the ability to keep your grades up is an important indicator of perseverance and of the ability to set and reach goals. Whatever profession you will end up having, you will inevitably have to do some things that you don't enjoy much. A successful person won't complain and throw in the towel if the task is boring - they'll suck it up and do it anyways. So your ability to go to boring classes is, in fact, an indicator of important personality skills that also contribute to your GPA.
It's sad if the educational system doesn't satisfy your needs, but you can still try to make the most of it and supplement it with your own education. That said, history knows plenty of successful college dropouts, so my advice is by no means universal. However, my suspicion is, a lot of people in the academia will think like me, so if you do want to get a Master's, it probably isn't a good idea to ignore the system altogether.
