I graduated undergrad last June from a T20 U.S. institution so no master's degree. My quant GRE score was horrible which is why I was so shocked but I have multiple journal publications and currently working as a lab manager for my previous institution within my field of study so I don't know maybe that made up for my gre scores.
Also, do not give up I've noticed that most admissions are sent out in batches so there is still hope! Wishing you the best of luck !!
