ur score is ok. i suggest you take a chance and apply for admissions. there is a lot of ambiguity this time in admissionz coz of the new format of GRE, the computer science GRE subject test being cancelled etc. and if u want to retake the test, try to figure out what went wrong and where. One problem I faced was taking too many mock tests so on the actual day the seriousness for the actual gre was not there at all. my score is 1230. and awa scores are awaited.
good luck, and r'ber GRE is not the end of the your admission chance. only one of the factors they consider. try to highlight other factors and make it seem as if this happened on a bad day.
