How should I fill out the end date for a one-year ED Visa application in Thailand?

When applying for an ED Visa in Thailand, it's unclear whether to put the course end date for a full year or just the initial 3 months. The school's documents suggest 3 months, which aligns with the visa's 90-day reporting requirement. However, one commenter suggested that indicating the full year is appropriate since that is the duration of your course, noting that you will likely receive a 90-day visa regardless. It's also important to remember that ED visas must be extended every 3 months.
