Who are the recent people who received ppr? Did you check on immitracker? Are the application from US or India? People from US may get in 2-4 months, but from India now I think it will take 5-6 months minimum. I'm not sure where everyone took their IELTS, but I took it in The Park Hotel Hyderabad, it was like fish market. Maybe not all are applying for PPR, but I'm sure the IRCC may have lot of students as well. Just that one day, there were more than 900 people at two centers in one city. Till we cross 5 months, no point in worrying.
