Before the test we were told that, if we passed the test, oath would be in 3-5 months. After the test we were given a paper in which the same was stated (3-5 months) and also had instructions for the ceremony; the Citizenship Officer said 2 months, but I was skeptic and indeed I was right. Since 3 months have passed since your test, hopefully soon they'll have a date for you.
