I bet you that by August, the cut-off would have dropped to 465. Not everyone can get into the pool as it was before. IELTS is not back in full swing. Many are stranded, cannot write CD IELTS, cannot travel to IELTS location as it was before, not everyone writing the general module and not everyone will be blessed with 8777.
2,5K per15 days is close to the pre-covid timeframe
Unless Indian universities send electronic transcripts, dudes cannot have their transcripts sent for easy processing. WES and CES will accept only if Universities send them the transcripts. I'm from Chennai and I have friends in TamilNadu, Karnataka, Andhra, and Maharastra. Many went to the universities of respective states and none of them were able to send their transcripts to ECA bodies. Although transcripts requests are accepted (minimum it takes around 30 days to get the transcript alone) and after that, it just remains in the university dispatch section waiting for Speed Post to resume In-university services. Honestly, universities have even more work to do than sending transcripts to ECA bodies.
Some physical transcripts that have reached WES or CES' office are being kept in the reception and will be worked on only when staff come to office (September end).
Plus, down south, IELTS CD tests are available in Bangalore and Hyd. Now Karnataka has gone into full lockdown. Not many are willing to write CD IELTS. Most states are into lockdown in India.
Situation in US is damn terrible
So once again, cut-off will drop to a good extent. That's my bet
2.5k candidates joining is a way too high estimation mate.
