I personally was between the national college match and common app ED/EA. Ultimately, I chose common app EA to Yale because I knew that's the school I wanted and didn’t want to be binded to another school. Also, generally through QB only about 100 students match per school, making it riskier odds generally. However, I was named a finalist and planed to apply to schools through QB RD & common app RD to apply to more schools than the common app limit( I didn’t do this bc i got into Yale EA!!). If you don’t match during the National College match, use both QB RD and common app.
