Stratoduck, Twin Wasp, Thank you very much for your kindness!!
I come to understand well about this matter.
It is so nice that I need not take another written test, and I can get ATP(AMEL) & A320 type at once!
I will look for part142 school and prepare for 8710-1 form by check ride.
Thank you Twin Wasp, for giving me explanation about Law.
It came to be able to read the law easily.
Are there any other subject should I check before joining Training center?
Is it enough? (Part61.64, 153, and 159?)
