MFin Admission Chances for Degroote McMaster University? Please help!!

I am applying for Masters of Finance program at Degroote School of Business, McMaster University. Any advice on my chances of securing admission will be greatly appreciated. Thank you all for taking the time to read this.

GMAT 640 (V35/Q42/IR4); Average (not median!) GMAT of Degroote's MFin program is 676!!!
I've got mostly 'A's and A- in my 3rd and 4th year of my Bachelors in Finance and Accounting from the Robert H. Smith School of Business, University of Maryland, College Park. My 3rd and 4th year CGPA at Smith was 3.67 (I got 4 Bs all in Accounting courses like audit and tax which brought down my GPA).

My professors at the Smith School have said they'll write me very strong recommendation letters.

I've also completed the US CPA exams. Had a straight 4.0 CGPA in my first two years of college though that was at a Community College (I think MFin programs might not care for community college coursework).

Extracurriculars:
One among two students chosen to represent the entire body of 27,000 undergraduate students at the university senate.

One among 20 students competitively selected out of 2400 students to become a part of a prestigious finance fellowship program in my UG.

Made it to the final round of a business idea entrepreneurial competition out of more than 260 students and presented my idea to members of the Maryland Chamber of Commerce.

Worked with the IRS as a volunteer tax preparer and received a certificate of excellence praising my work ethic.

Worked in a small company to get experience of how the businesses function overall. My passion entrepreneurship drove me to join this company. I got good experience here. The MFin program at McMaster does not require any experience though.


Degroote has 3 rounds of admission for international students and while the first round has passed (December 01, 2019), the second round of admissions deadline is January 15, 2020 and the third round of admissions deadline is February 20, 2020. Now since today it is already December 06, I feel that even if I do retake the GMAT, it will take GMAT 3 weeks to send my official report to the Degroote school of business and it must reach the school BEFORE the second round of admissions deadline of January 15, 2020 for me to be considered in that round for admission. That means I should at most take the GMAT exam by December 24, 2019 and that gives me only 18 days more from today to study for it and improve my score. If anybody can give me any advice regarding how competitive my score of 640 (V35/Q42/IR4) is for the MFin at Degroote, I'll be extremely grateful.

The mean (not median!) GMAT score of Degroote's MFin program is 676. So I'm 36 points below average. I think my CGPA of 3.67 at Smith and the fact that I've passed the US CPA exams should at least demonstrate to Degroote's MFin that I'm capable of handling quantitative coursework even if my GMAT is 36 points below their average. But what do you all think? Should I retake the GMAT by December 24 to apply for the second deadline? Or just concentrate on the rest of the application (Statement of Purpose) and pray that my GMAT of 640 is good enough for the second round of admissions. Also, I asked Degroote if applying before the second round of admission of January 15 would increase my chances of admission as compared to applying before the final deadline of February. They just said "We cannot say that your chances would be higher. Depends on the applications."
