I just took my PMP course at Chicago Training Center and passed my exam on first attempt. They have shifted to a new location and facility is much better than the previous one with lot of parking space. I did have some issues with old staff but now they have all new staff who are very freindly and helpful. Their programs are also approved by many reputed US based universities and participants are eligible to get the certificates from these Universities. All in all, I had very good experience with them.
