Hi,

i have a query regarding my official GMAT score report. While registering for the exam, i was not sure about the conversion so i used the table mentioned there and marked my GPA as 2.5 for 75%. 

Later after i gave my exam i came to know that it is not the correct conversion criteria and my GPA would be somewhere around 3.0-3.3. 

i got a score of 730 and 5.0 (AWA) .. GMAT has mailed my report to the 5 schools i had mentioned during the test.

Does this harm my application in any ways ?

should i get it corrected ?

Please advice ..
