Keep or Cancel 620 GMAT Score

Hi All,

I took the GMAT exam on Saturday for my second attempt. I am still in the 72 hour window and given some background info below, I was hoping to get some opinions on what to do with my score.

-I graduated from Penn State in 2014 with a degree in Finance (3.71 GPA)
-I have 5 years of work experience in Private Wealth Management (portfolio management specifically)
-I am a CFA Charterholder
-I first attempted the GMAT in 2017 with hardly any studying and received a 530. At the time I wasn't committed and quite honestly didn't even think to cancel my score, so it's still on my record.
-I decided in 2019 I am committed to going back to school and getting my MBA, so I studied for 3 months this year and received a 620 (Q44 V32) on Saturday.
-While my dream target score is 700+, I feel that I would be happy with a 670 or above
-The schools I am targeting are UNC, Duke, Michigan, Carnegie Mellon, Virginia, Georgetown etc. If I did good enough I would target higher ranked schools, but I am comfortable with the schools I listed.

I am struggling to decide on cancelling this score. I know I can raise my score but I also feel that progression looks good. For example, my thought is that schools would like seeing the commitment. Say I went from 530 to 620 to 670/700, I think that shows shows my dedication to this exam.

I also feel that a quant score of 44 is decent. I hope to improve it, but the off chance that I do worse next time around, I would want schools to see that I am capable of a decently strong quant score.

Any opinions would be helpful.

Thanks so much!
Dan
