100 to 500 upgrade

From what I understand I can go from 1 to 500 with 1080 days and 720 over 50 grt. Getting all my pre recs out of the way so I can qualify to test. All my tonnage is under 100 grt, wondering if this will be a problem or is what the National maritime center checklist is correct? Any help would be greatly appreciated.

The checklist is still valid…for now. Just be sure to have everything on the checklist completed that is required; (as in recent First Aid and CPR.)

Do some searching on the forum and you’ll find numerous threads on the subject.
