Ok, just to start off, CS is a Limited Enrollment Program {LEP) along with a number of other majors.
This means that they do not have the physical resources (classrooms, labs, professors, etc) to support all of the applicants who applied for that major.
So. some number of students are put into L&S and can do an internal transfer into their desires major. These students have to take what are called “Gateway” classes, achieve a certain GPA (it varies with the major), and then fill out a transfer application.
For all majors, except Business, it is a routine process. The UMD CS Department even has an FAQ page which states “Yes. All students who successfully complete the gateway requirements will be admitted to the major.” These Gateway courses are the EXACT same courses that all direct admit CS students take,
Some students are also invited to join Special Programs, Honors, Scholars. FIRE, etc. Many of those programs have associated dorms. All the students in a given sub-program live in that dorm (i.e. Honors has about 7 or 8 subprograms for students to pick from).
That can be nice to start, but it is not necessarily permanent. My D and her roommate lived in Hagerstown Hall freshman year (the University Honors subprogram). It was not a great dorm (no AC). The next year they moved to Denton Hall.
FIRE seems to be a Great program but it does not have an associated dorm. I don’t know why. But,iMO, the chance to do hands on research is a terrific opportunity,
You asked if some program are better than others. Many people perceive it that way. It is true that the Honors College has the first pick of students. But I think that overall, the AO’s are looking for students that they think will fir well in each Special Program to the mutual benefit of the student and the program
Finally, I believe that it’s important for each student to take advantage of all the opportunities that are available at UMD.
My D was in L&S and transferred into a LEP at the end of her First Semester. The young man who became her fiance transferred into a LEP at the end of his Freshman year
In the DC area, you can’t throw a stick without hitting someone looking to hire people with CS degrees.
I hope this helps
