I’m challenging now

I want to get more licenses. One of the licenses which I want to qualify to be a handler of dangerous materials. With the license, I will be able to handle dangerous chemical substance. I think it will be useful for my work.
Its’ difficult for me to pass the test but enough study can get closer to a pass it. I want to learn a lot of other qualifications as much as possible.
Then, I’ll make an effort to raise my skill.
