I am really disappointed by the duggans course....i took this course in april 2009 for my colorado interview, it was a 9 days intense course....but i dont think dr. duggan is doing the justice to the international students ..he charges so much money and still doesnt give you the attention u need to excel,,,its just a buisness for him, all he is concerned about is your money...I had 3 students with me and none of us got acceptance. two of my friends failed wreb even after spendind $5000.. rest its ur discreation, if you have choice take sme firend's help and practice at home, duggans course is useless....no offence but it might have been useful to some..but in my opnion its not worth it
