The challenge for me is to take a tutor course, because studying the field of gems is very new to me, and I feel that I have less background than others, so it is difficult for me to understand it at once. So I must try to learn more in the study materials of GIA course and ask my friends in the team, which will help me to have a great understanding of the contents of gems. As a result, I can now complete the AJP course, and now I am studying in the introduction of diamonds and diamond grade courses.
