Thanks for your question. I think, the most critical thing for such programs is the type of financial aid you are seeking.(grants and loans, as opposed to scholarships/ellowships) Having good grades will most certainly gain you admission to many of the lesser competitive schools with the acceptance rate you indicated. BUT, you will be in direct competition with those with the highest marks. Put it this way, for every top student who goes to say Harvard, Yale, Princeton, (or in the UK, Cambridge, Oxford, UCL, King's, etc.), they will NOT all be getting the full scholarships.)
Top students and very good level students sometimes will end up going to the less competitive programs because they are being given everything (full tuition, full housing costs, labs, fees, books, sometimes a stipend,etc.) whereas, at the top schools, a very good candidate might get some partialscholarship assistance, but the top students are getting the full scholarships at the most selective schools.
However, in the United States, there can be a great equalizer, and sometimes, even a greater advantage in the standardized test scores. Take a good student, who makes all B's or merit level. Bu that good student has a top ten 10% test score, he or she can then largely stand on the equal footing with the very good student, who has very good test scores, just maybe not quite that high. Additionally, the very good student(and this is just an example) with a top ten % test score, who did absolutely nothing else, no extra-curricular activities, no community involvement, well, weigh that against the good student who has measures of all of those things, perhaps had hardships, or has some unusual background(a good example is someone whose parents served in some position or job that had them moving all around the world, but there are many others)-may very well be ranked above the person with better grades and the same score. So the critical thing to getting money at the lesser competitive schools-potential scholarships (as opposed to traditional debts) will be how well you do on the SAT, PSAT, or ACT-whatever the case may be. So that to me, is the most critical part for schools that are not the most competitive-high test scores, good student level-not superb, not very good(but obviously, the more the merrier!
