Is there time still?

I have preboards in 16 days , i didn't take the midterms seriously and plummeted to 3rd rank from second and didn't study anything for the preboards until now , even now I'm not serious. But if I maybe start studying my ass off can I get rank 1 , which is held by a ratta mar girl who gets between 75-79 out of 80 every exam. Chat can I clutch it up
