Odds ratio

How do I interpret odds ratio that does not seems to make much sense? I am studying the relationship between time taken to complete a STEM degree and a lot of independent variables (gender, race, SAT scored etc).

So my odds ratio for SAT scores is -0.001 which can be interpreted as for every 1 point increase in SAT scores, time taken to complete STEM degree decreases by 0.001 years, which comes down to about 0.36 days which is clearly ridiculous! Please explain how to understand this better. Thanks!
