My two cents on this (obviously biased):
Lots of applicants focus on rate but it's worthwhile looking at the process different Admissions Consultants follow. When the process is more efficient, you get tier 1 level support but a far lower cost. We achieved that by focusing on a 3 part initial 'experience brainstorm' (hence the name 3Storms) which generates so much modular organized content for every essay question, school selection decision, recommender question, video essay etc. that the rest of the process accelerates . Other consultants may have a different approach to streamlining the process. All we know is that a top notch application coaching service for 3 schools should cost 1/3 of what many charge simply because of the process being more efficient and cutting iterations by 60%.
Happy to discuss further on a FREE first brainstorm session.
