Can I claim regional points?

University Tenure: Location: Adelaide, South Australia Commencement: 16 March 2020 Completion date: 8 November 2021 Semester studied: 4 semesters with a full load CRICOS duration: 6 academic terms

Confusion: Since the start date and end date on my completion letter are not indicating 2 years time, but I studied 4 semesters in Adelaide and completed my Bachelor’s in SA, am I eligible for regional points? A few people told me not to claim regional points because the visa officer only focuses on the start date and end date. Need help if anyone experienced it. Thanks in advance.
