quick and dirty estimate of MBE scaled score based on raw?

After a significant amount of googling I can't get a straight answer on this....

Using Themis prep for the MD bar. My MBE RAW scores are now consistently in the 135-145 range, usually about 139 (out of 200 practice questions, mind you. NOT out of 190 as it will be on the real exam.) I find the essays in MD really tough and arbitrarily scored, so I'm trying to get a sense of how I need to perform on those essays given my MBE raw score. I have found MD's rough formula for scaling the essays but can't figure out a good approximation for scaling the MBE. I know it changes every year, but even a low estimate would help. Should I add five points? ten? Themis doesn't tell you much only gives you a "goal" of 70% correct which is not met with a 139 so I don't know whether to feel nervous that I'm not there.

I know an answer to this ultimately will have no bearing on what happens in reality, but I'm just the sort of person who likes to know my chances ahead of time...If you have any idea how to roughly convert a Themis practice MBE score to a scaled July MBE score, please share your thoughts!!

Add 15 to scale in general, but I don't know how to adjust for Themis's difficulty

Thank you! Virtually all Themis MBE questions are from old exams so hopefully it is comparable. But you add 15 despite it being out of a 200 question set as opposed to 190? That seems generous. If that's right then I should be in decent shape though phew!

15 is what I've been using as a rule of thumb for the raw -> scaled conversion for the actual MBE, so that's out of 190. I'm not really caring enough to actually average recent mbe conversions or adjust for 10 less questions somehow. Make it 10 if you want to be conservative, I guess?

Gotcha, that makes sense. I just like to have a feel for where I am. Thanks!

I just googled and found this: http://one-timers.com/wp-content/upload ... -Chart.pdf. Don't know how accurate, but looks like it's probably pretty close.

Wow that's more generous than I was expecting

Wow! This would come out to just under the plus 15 estimate (more like plus 11 or 12), so it seems reasonable. Thanks! I couldn't seem to find anything like this anywhere. I know it changes from year to year but I figured there HAD to be some sort of decent estimate out there.

So you're in the raw 140's-150's?

You're gonna pass this thing!

I'm shooting for 2/3 on all sections, so I'll hope for 110-115 (raw) and anything else is "extra" to help on other sections.

139/200 = 69.5% x 190 = 132 raw - on that conversion chart you're looking at about a 147/8. It's impossible to know how Themis stacks up against the real MBE though.

Good call with converting it out of 190 like that. Hopefully Themis should be roughly accurate since its primarily old MBE questions. If I hit that number I *should* pass (knock on wood) despite my terrible essays so here's hopin.
