CIM reference letter

Hi everyone! Anyone here applying to CIM or is already in CIM? May I ask regarding the letter since its sealed by the professors how will you pass it as a soft copy together with your application form? They also already emailed it to CIM.

"Letters must bear the official school letterhead and the official academic email address of the professor making the recommendation. Incorporate the letters with all the other documents, both physical and electronic." - I really don't understand this. Is this for the good moral cert?

Also, How can you pay the application fee through Gcash? Will I send it through bank? Hope anyone could answer😊 Thanks in advance!
