I don't have an official starting score, but my sense is that most of my students are scoring in the 550-630 range when class starts. I do have people higher and lower than that, but most seem to fall into that range.
If you're already at the 650+ level and are looking to push your score higher, then you might consider our Quest for 750 workshops instead of a full class. There are three: Sentence Correction Slam, Advanced Data Sufficiency, and Advanced Quant. (See our web site for full detail on the workshops.)
Just a note of caution: if you aren't already at a 650+ level in the respective areas, then the Quests will likely be at too high a level for you. The instructors assume that attendees have already learned everything necessary to get to that point, and the class takes off from there. The vast majority of the questions covered are 700+.
If you're not yet at that level through self-study, then you would still get a ton out of the classes even if you have already gone through our study guides and OG - in fact, with the instruction, you'll probably need and want to go back through a lot of that material in order to get everything out of it that you could be getting out of it - which is tough to do without the instruction. (I don't mean that you can't study from our materials without the instruction - you obviously can - but to get close to 100% usage out of the material, you also need the instruction.)
FYI: the bootcamp is the same curriculum as the regular class, just compressed into 2 weeks. Even if you literally have nothing else to do during that two weeks, it's still tough (in my opinion) to absorb the material well in such a compressed timeframe. I know I'm talking about my own company's offer, but I still wouldn't recommend bootcamp to anyone unless they had to take the test in two weeks and this was the only way. If you have the time to take a regular course and work through the material more fully, then do it that way.
