Step I Step 1 NBME question

[Phenytoin]

Hi guys,
I am taking Step 1 on June 17th. I took NBME 1 a week ago and got a 510 (225). Is performance on form 1 (i know it is the oldest and easiest) representative of what would happen on the real exam?
I will have 6 full weeks after finals to dedicate to this exam. What can I realistically increase my score to?

Thank you for your help!

I also began at a 225, I went up 33 points to a 258 in 8 weeks.

I think NBME #1 has significantly worse predictive value than the others. Unfortunately I think it tends to overpredict.

Fortunately, 6 weeks is an eternity.
