There's this well known graph you can roughly use to get an idea. I would apply 10% error margin (give or take) - just because step 1 has a bit different emphasis on biochem, pathophys as compared to level 1 (comlex) that tends to test pharm and micro a bit more. But purely for comparison purpose - you are at about 220-225 roughly. Which IMHO is not a bad idea for you to take step 1 - depending at what specialty you are aiming at.
