Not all MSN programs require students to submit their GRE scores. Some schools typically waive the GRE requirement in certain cases, such as if the student has successfully maintained a GPA of 3.0 on a 4.0 scale. Numerous colleges across the US are offering admissions in their MSN programs without the need for GRE scores. Students are advised to check the admission requirements in detail for any institute they consider applying to in order to ensure all requirements are met in time. If you must take the GRE, make sure you register well in advance so that you can get the results in time for the admissions deadline.
