這是我寫的一個英文信可以請大家幫我看一下嗎?我要跟一個老外通信?

HELLO PRASANTHEN,I HAD CORRESPOND WITH YOU BEFORE ABOUT THE
BEFORE可以用在過去完成事嗎?
QUESTION OF IMMIGRATION SKILL ASSESSMENT,I DONT FULLY UNDERSTAND THE FORM AMSA12.PDF OF ESTEEMED AMSA

THE (f) ITEM IN THE PREREQUISITES OF AMSA12.PDF REQUIRES I MUST HOLD A
(BELOW IS IT S ORIGINAL)evidence of shore based practical workshop skills training as specified in relevant sections of STCW Code Table A-III/1 column 1.

THE QUESTION IS I DONT HAVE SUCH A LICENSE,CERTIFICATE,OR A PIECE OF PAPER THAT WAS ISSUE BY A SPECIFIC TRAINING CENTER OR ORGANIZATION.THE REQUIREMENT FOR THIS TRAINING WHICH IS RELATED WITH(我符合用RELATED WITH這樣好嗎?) THE relevant sections of STCW Code Table A-III/1 column 1 IS EMBEDDED IN OUR CURRICULUM(我用CURRICULUM來表示大學或者是專科一個系所裡面的所有的課程這樣對嗎) OF MARINE ENGINEERING.
AND,WHEN A STUDENT GRADUATES FROM THE DEPARTMENT OF MARINE ENGINEERING,HE CERTAINLY AND AUTOMATICALLY FITS THE REQUIREMENT FOR CERTIFICATE ISSUING OF STCW. THAT IS WHY I DONT HOLD A CERTIFICATE, LICENSE OR WHAT EVER OF PIECE OF PAPER LIKE THING.THE ONLY EVIDENCE I CAN THINK OF IS THE GRADUATE TRANSCRIPT OF MINE.BECAUSE THIS TRAINING IS EMBEDDED IN OUR CURRICULUM,SO THERE IS A SUBJECT NAMED WORKSHOP PRACTICE IN THE GRADUATE TRANSCRIPT,ALTHOUGH IT S IS NOT THE SAME WITH THE NAME WORD BY WORD(一字一字地一樣) THAT DESCRIBED IN ITEM(f) OF PREREQUISITES,AND OF COURSE,I PASSED THIS SUBJECT.SO CAN MY GRADUATE TRANSCRIPT BE A EVIDENCE TO PROVE THAT I HAD COMPLETED THIS WORKSHOP TRAINING OR SHOULD I PROVIDE MORE SPECIFIC CONTENT OF THIS SUBJECT?
IF AMSA DO NOT ACCEPT THAT MY GRADUATE TRANSCRIPT CAN BE A EVIDENCE OF THIS TRAINING,DOES AUSTRALIA HAVE ANY MARINE TRAINING CENTER OR ORGANIZATION TO PROVIDE SUCH TRAINING SO THAT I CAN JOIN AND GET A EVIDENCE THAT I HAVE COMPLETED THIS TRAINING ?
THANK YOU FOR YOUR PATIENCE,AND SINCERELY WISH YOU A GOOD DAY.
