I did my test on 20th August 2015. I am wondering how long after that I have to wait for decision made?
Should be within 2 months I think.
My test date was June 22, 2015.
After test, CIC sent me CIT0520 form twice asking different documents for additional evidence (due to my mistake calculating physical presence).
First letter was sent July 17, 2015 (3 weeks after the test) asking my travel history to the US
Second letter was sent August 10, 2015 asking my employment letters.
I did not know when exactly my status in ecas changed to "decision made" as I rarely checked the site after the test.
But when I checked on August 23, 2015 the ecas status said "decision made".
I did not receive the oath letter dated August 31, 2015 until September 2, 2015 last week.
So since you did not make any mistake like i did, I would assume yours will be even faster than mine.
Do not fret too much. Within 2 months all will be over
Good luck
