I really recommend Amlotus for studying IBT-TOEFL, especially DJ Kim !!
I was struggling with the speaking score, but with him, I improved 4 points only for TOEFL speaking section in 5 weeks. He is very skillful and professional!! I studied at many other schools in New York and even at Hackers in Seoul, but DJ Kim is the best!!
