Numerology is a sub-branch of Astrology. Unless your trainer is not an Astrologer - he won't be able to teach you Numerology in it's genuine and purest form.   Beyond a certain limit, he / she won't have a clear and satisfactory answer to your questions.   A simple test is: If you remember (or can revise) what was taught to you WITHOUT GOING THROUGH EACH AND EVERY WORD FROM THE NOTES or referring to a software - you've learned from the best!
