As you Know SSC CPO is an exam for SI in Delhi Police as well as SI in CAPF however the seats for SI in Delhi Police are very low so the cutoff for it goes very high.
As CPO has 4 levels and out of which level 1 and level 3 are conducted through online mode. Levels 2 and 4 are physical and medical tests.
Level 1 and level 3 have 200 no. each and a total of 400 no.
As SSC releases different cutoffs for MALE and Female for a particular post.
Now talking about the expected cutoff for Delhi Police for a UR candidate, if you are a male you have to score a minimum of 340-350(normalized score) and if you are a female you have to score a minimum of 300-310(normalized score) for a post in Delhi SI.
Note that this prediction is based on the latest year trends and you have to be physically and medically fit for the post along with the marks.
