I submitted my work experience on January 3rd, 2019 and still have not received THE email. Meanwhile, I wrote twice to GARP to inquire about the review process (2nd time this morning) and this was part of the answer I received today: " ... due to the large number of experience submissions it is not out of the realm of possibility that an experience review can take 1-2 months to complete".
So it takes GARP 6 weeks to release the Exam results but up to 2 months to review the professional experience ... It's disappointing. CFA Institute was able to review my experience in less than 3 weeks back in 2013.
6 weeks is pretty reasonable already considering it is scantron
