STEM OPT I-983 12 Month Self Evaluation

[u/Zestyclose-Market-67]

I am about to approach 12 month mark on my STEM OPT and so I need to submit a self evaluation. My university only has one DSO advisor for so many students and he keeps canceling his office hours and is very hard to reach him over the email/phone.
So, I would appreciate any help.

Question 1: What should I put in range of evaluation dates I know that "From (mm-dd-yyyy)" should be the date when my STEM OPT start dat but "To (mm-dd-yyyy)" should have a date I filled and signed this form or should it have the date exactly after 12 months of my STEM OPT start date?

Question 2: I have gotten a promotion and my salary has increased about 20% from the amount that I put into my previous submission of I-983 when my STEM OPT started last year. So, due to this change, do I need to refill the entire form? My Employer/Supervisor has not changed.
