Thanks for the site.
The Bar Chart by Total College Enrollment says there are 11,103 students in the College of Computing and 14,142 in the College of Engineering. But digging further, I see that 8,361 are in the Master’s program in CS, and I know that GT has an Online Master of Science in Computer Science program.
For Spring 2019, I see 403 undergraduate degrees from the College of Computing, 1243 from the College of Engineering, and 194 from the College of Sciences.
Some people in the thread http://talk.collegeconfidential.com/georgia-institute-technology/1888242-myths-of-gt-admissions.html said it was more difficult to be accepted as a CS major but that it is not difficult to change majors once enrolled.
