Thank you Henry,
Actually videos helped me to remember ITTOS,It will be more easy if you learn exactly what it signifies then you will able to remember where it use. Also please try to make table yourself in the paper two three times,every time you will see where you missed and do various practice test . I used 000 questions from Christopher Scordo ,did various free simulator site,finally pm prepcast simulator before the exam,last two weeks.After complete various practice test you will remember almost all ITTOS. But I used only pmbok 5th edition and PM Prepcast training as reference.
Thanks John
