Sure. I believe ManhattanGMAT offers exactly this service in Manhattan ONLY. You can call the student services number to schedule an appointment: 800-576-4628 The test center is located here:

Thanks for your response.

I just inquired. It is open only for their students of 9 session prep course. Very unfortunate. Manhattan GMAT(Kaplan) can make loads of money if they conduct such test series. Only issue for them I guess is the space in NYC. If that is the only reason, schools' class rooms can be used on weekends. Students can anyway get their own laptops/tablets.

Rats, that's too bad. I'll look into setting something up for non-students. (Nothing will be complete in time for you, unfortunately.) As one data point though, what would you pay for a simulated GMAT?

It seems it is not a bad idea to practice in noisy places as GMAT test centers can get really noisy at times.

@Tom: To your question - Any ManhattanGMAT book of $26 comes with 6 exams. If you add $75 for simulation(including noise), total package of $100 looks attractive. You can just let students book the slots online, just like GMAT.
