It depends on your ranking board and your unit.

The principle of ranking is comparison with your units. Here are some of my personal thoughts:

1. Projects need to have a outcome/ product. Work in Progress projects usually have no weightage.

2. You can do a lot, but if your unit’s colleagues do a lot more then they may be ranked better than you.

3. There’s a perf grade quota — meaning the grades given to your unit is fixed.

4. Ranking style of the board plays an important role. Some commanders give emphasis to help people who can be promoted, some are more work objective based.

But first full year ranking C is quite common because there may be a lot more older officers in your ranking group.
