진로 = generally a path of movement, but also a choice you make for your career or education (going to school, getting a job, etc). 진학 = going to a school for your next level education, like going to college after graduating from high school. 박람회 = a fair or expo. So 진로 진학 박랍회 is like a "education and job fair", which would be a fair showing and offering graduating students choices for their next move.
