Hey, Greg, Can you provide us some channel where can send the recording of speaking tasks for evaluation. This feature is lacking. It is quite costly test so we need to verify our performance before purchasing it.
I mean you can post it under the TOEFL channel but then again you’ll need someone who is willing to grade it; it’s the same thing with essays , no ones want to do it because it requires too much of work/effort (I personally blocked the essay channel 
because I’ve no interest in grading essay).
Best solution is either to find a study partner or pay for the service or just grade it yourself.
