Can the dreamweaver program be used for part time web design jobs?

I really want to know if the dreamweaver program can be used for a part time job because im still in highschool and want to go collage for webdesign so i figured it would be a good job.

Can you take web design and graphic design classes at the same time?

Is it possible to take web design and graphic design classes at the same time? Also, for schools like “The Art Institute”, how many classes can you take?
