I think that you need to be a little realistic here. If you’re applying for Columbia engineering (where the CS department is), you will either have to send in your ACT score or your SAT and SAT2s in math and a science. Even if you only send in your ACT score, there will be many qualified applicants who will send in strong SAT2s and I suspect you will be at a disadvantage. I’m not entirely certain why you think you need another reach; moreover you don’t seem to have a firm idea about what you’re looking for other than a reach school (Dartmouth and Columbia are VERY different schools). I would probably focus more on schools that are matches/slight reaches and that fall somewhere on the level of RPI - Rochester, Brandeis, Barnard etc.
I think computer science is a major within Columbia College, Columbia University’s college of arts and sciences.
This will be easier to answer when those scores come in. I know you have focused on the East Coast, but any interest in Harvey Mudd if your scores are really good? My D2 is a junior there and adores it. Extremely strong CS, a tech school that has a strong cohort of female students (about half the class), and part of the Claremont Consortium of 5 colleges (so you get some of the benefits of a bigger campus while attending a smaller school). It is a really challenging school, but also a very collaborative environment. They gave my D from the Midwest a travel voucher to come for accepted student days when she was admitted, so even if you haven’t visited, it is worth a shot.
intparent - I believe that the OP’s scores came in this morning and they are all under 700 - here’s what the OP posted today -
I did really bad on all of the subjects that I took… I really would rather not send them. I was surprised, I thought I did so well. I’ve never beaten a 700 on a subject test, and I’ve taken 5. I’m really disappointed. Will my application be damaged too much without them?
And merci, I believe we are both correct. A B.S. in Computer Science is offered through the Fu School of Engineering, but Columbia also offers a B.A. in computer science through Columbia College.
Your parents have some strange opinions. What’s wrong with Brown? (Though I know from our school students with your stats don’t generally get in.)
Pittsburgh is really a nice city. I know CMU’s CS program would love to have more women, but I agree with you that they will probably be put off by low SAT scores in math. CS also has a really low acceptance rate - of all the CMU schools I think only drama is harder to get into.
I agree that Barnard is worth looking at - be aware that you need to understand what Barnard is and want that. They don’t want students who just see it as a back door to Columbia. I do think it can supply the best of both worlds - nurturing LAC plus access to one of the world’s great research universities.
Agree with others that U of Rochester is worth a look. Northeastern is known for co-ops - if that appeals you should look at it.
Since you are into a safety already, you can aim as high as you like.
@mathmom I agree, my parents are totally weird, lol.
I am focusing on reach schools because my GC told me to. I’m seeing everywhere and from old threads that I basically have no chance at all. Are my stats really that bad? I know my math is slightly low but I’m retaking in December, and I thought a 2180 was respectable… And I thought that all my outreach efforts and the fact that I have published research might help a little… I’m not saying I deserve to get in or anything because I know that’s foolish entitlement and whatnot, but do my stats really push me out? I didn’t think they were that strong but I thought they were decent enough to put me in the ballpark… One of the other GCs at my school told me that I shouldn’t even bother, but mine told me I should so I don’t really know what to think.
I’m looking for selective schools that don’t require subject tests (my scores were 670 and 690) and that’s why I was leaning towards Columbia. I don’t understand why if I send the SAT and the ACT then they still require the subjects, but if that’s their policy then I will have to either comply or find a different school. I know that Tufts and Penn require all tests and I will send all to both and hope for the best. I don’t think it will hurt me for Tufts as much, but Penn seems like a long shot. I don’t think I’m even going to try for Princeton anymore.
Your math is not that bad. But especially if you are trying to sell yourself as a potential CS major it could be an issue. My younger son got into U of Chicago, Vassar and Tufts with similar scores. (790CR, 690M, 690W), but that was five years ago and no question being male helped at Vassar. His teachers and GC wrote great recommendations, his essays were very good I thought, and he had some quirky activities that were not just run of the mill stuff. He wasn’t a STEM guy, but nevertheless had a bunch of Science Olympiad medals and was in two orchestras all four years of high school. I don’t think your chances are zero, but much will depend on how you come off on your application and that’s what we don’t see. Your math score is in the bottom 25% for very selective colleges, but there are plenty of students even at Harvard and Yale with math scores in the 600s. I don’t think they are all athletes and development cases.
I’m having trouble figuring out which colleges are truly don’t require subject tests. A lot of schools say they don’t, but CS falls under engineering and then they require engineering students to take a math and a science. So I don’t really know. I would love to apply to JHU and they say that they don’t require them and that your application will not be hurt without them, but then it said that engineering students are “encouraged to take math 2 and one science test”, so I don’t really know what that means.
Universities:
Carnegie Mellon
Tufts
Rochester
Brandeis
Case Western
Boston University
Boston College
Lehigh
Northeastern
Small liberal arts colleges:
Vassar
Hamilton
Wesleyan
Colgate
If you are open to all women’s colleges:
Wellesley
Barnard
Smith
Mt. Holyoke
Bryn Mawr
Holy Cross in Massachusetts would be a good choice-great school with CS major. Hc has beautiful campus 1 hour from Boston.
I like Case Western, it has all of the programs I’m looking for, and no application fee is a plus. Is it good for CS?
Would I have a good chance of getting into Case?
^yes it’s excellent and a very good idea!
@anon9632 Is location an issue for you? I can make some recommendations for you from my “list” of computer science, computer engineering and ai schools.
@OwlGuru Location is kind of an issue, and my parents aren’t totally comfortable with me straying that far from NY but they said I could apply because of the free applications 
I’d appreciate recommendations if it isn’t a burden 
@harvardandberkeley your list was very helpful. I am applying to Tufts and I just added Case Western. I had actually visited Boston College when I was in the area visiting Tufts. I thought the campus was beautiful, but when I found myself in a sea of young men wearing salmon-colored shorts and boat shoes, I decided it wasn’t for me. It’s an excellent school, though
Thank you all for your help!
