I really would like to post my own experiences because I know how helpful other people sharing their experiences helped keep me in perspective and realistic. So here is all the information on my own process.
Eligibility criteria - Long residence (since 2004) but used marriage to a British citizen as route + ILR obtained in 2015
Language criteria met: Life in the UK Test + BSC & MSC both in UK universities
Nationality: Non-EU
Method of application: NCS + JCAP
Date of application: 17/03/2017
Payment method: Debit Card
HO deducted fees: 22/03/2017
Email acknowledging receipt by HO/UKVI: 23/03/2017
Date of letter requesting biometrics received: 25/03/17
Biometrics done: 27/03/2017
Letter from HMPO requesting passport payment (because i filled in the wrong payment details & transaction could not be made) received: 05/04/2017
Called HMPO to pay over the phone: 06/04/2017
Dare of approval: 17/07/2017 (Exactly 4 months from application)
Letter of approval received: 22/07/2017 (exactly 4 months from fee deduction)
Letter of invitation to attend citizenship ceremony received: 22/07/2017 (dated: 21/07/2017)
Date of ceremony: 02/08/2017
Date passports received: 11/08/2017 (issued: 10/08/2017)
Please I want to add that I did not receive any text or email from HMPO advising on passport dispatch or progress status. Passport came automatically after attending ceremony. I hope this is helpful to someone because at many times I was looking for any indication to know when to expect it. (It came exactly 9 days after ceremony which includes weekends)
Best of luck!
