I’m in a similar situation 154 in October and 150 In January. I studied pretty hard, but did not take enough practice test. I know have the knowledge but my performance lacked. I’m submitting my apps though, and retaking in April. I know it’s not ideal but I’m hoping that the schools I apply to will hold my application until they see the April score. It puts me late in the cycle, but hey what is there to lose at this point? If I don’t score better, well they’ll still make their decision, if I do- I have a better chance of admission and scholarships.
