So I had this exact issue when I was applying for Nova. My score remained at a stubborn 293 after 3 times of taking it. I had given up and cried that third time and swore off taking the damned test again. It was November and the clock was ticking. I knew Nova wouldn't take my 293 because it was under the cut-off. In short, I stopped crying, bought magoosh for a month and eat, slept and breathed the quant section (my verbal was a decent 155 and my writing a 4). I brushed my teeth for 1.5 minutes every day so I could accustom myself to the length of time I should spend on a question. Crazy I know. But, I did what I had to to succeed in a month. I took 4-5 practice tests. In a month, I retook the test and scored a 304. I had a 12 point increase. It takes dedication and it wasn't easy, but it was seriously possible. Did you interview with Nova at all? And congrats on your other acceptance! Let me know if you need any advice.
