I'm a fresh graduate from a B.S. in mathematics program and am looking to go to graduate school. I have a strong cumulative GPA of 3.7 and have secured 3 letters of recommendation for the future. Despite this however, a mandatory 1 year military service program prevents me taking any GRE exams before most application deadlines. I was planning to apply during my service and start the following fall (2019). But I'm afraid that not having GRE scores will significantly hurt my chances. Should I just take all my GRE exams during my service and apply for the fall 2020 term?
