If you don't mind I would like to say something, the 3 courses you are looking into all of them are in the price range of 1500+. You might as well take up a Private Tutor.
I am an avg student trying hard to cross 600+. I took a similar course and did not work.
Now I have started re-doing the OG over and over again, with a Private Tutor for the same price (maybe had to stretch a bit) it has worked well. I know my mistakes, I know my weaknesses.
I have a game plan, and the rest to left for luck.
I wish you all the best. I can send you contacts of the PT's please send me a private email if you need their info. Reasonable guys (Esp the quant), and do a good job.
Regards,
S
