Never give full And right information. Just heat up and confuse mind with information at first. Then give something right information near to knowledge. Then right and good information will be made to learn by self effort. MY TEACHERS USED TO SAY WITH ME THAT KNOWLEDGE IS NOT TO BE TAUGHT BUT WILL BE MADE TO LEARN BY SELF. Without developing intuition in subject,there is no point. in teaching subject. A subject of course is not right and good for self "but to make self as self within self". For example,it looks wise to make a student learn engineering or medical course. But that it is wise to learn that engineering or medical course is meant to make self as self. That means a student is not supposed to learn subject course beyond his/her parental profession/occupation.
