Not necessarily, but we do use past performance as an indicator in determining if you are up to meeting the demands of graduate level study.
A lot of people who do extremely well in graduate school have undergraduate grades they might be less than proud of. Don’t try to hide them. Don’t decide not to submit a transcript just because it reflects progress in an unrelated field or a degree you didn’t complete. Address those issues in your letter of interest and speak to both your desire to make a stronger showing in this program and discuss some of your strategies for doing so.
Don’t obsess about past grades. The quality of your writing sample, strength of your letter of interest, and the enthusiasm of your references will likely outweigh that D– you got in calculus.
Often I hear people stressing over their resume or CV… even about what the difference between a CV and a resume is, and which one is appropriate, how long should it be, and how much not having a bunch of professional credits on it matters.
To all that, I can only say, “Relax.”
A resume is geared more toward employment and a CV (Curriculum Vitae) is geared more toward academic achievements, so for this program resume is probably more appropriate, but that doesn’t mean the academic achievements are irrelevant.
As for credits, we don’t want you to prove you don’t need the instruction in order to get into the program. What we want is an accurate idea of your background, where you’ve worked and what you’ve done and who you’ve done it with.
Be truthful. Be complete. Be concise.
