I graduated in 2017 under 4 year degree programme batch. IN 2023, many of my batch mates gotten the promotion to a GEO 4 but I was not considered for promotion. I suspected that I gotten my C- for the year in 2020. If like what Louis Ng said is true, means I wont be considered for promotion for the next 3 years. However, for the past 3 years 2021, 2022 and 2023, I have been consistently getting C grade. Can I still promote this year? This is really frustrating and demoralising.
