Errors made on online form - cover letter fix?

Hi all,

I’ve submitted my online application and realised I made a few silly errors. UKVI have advised I cannot amend online and suggested I do a cover letter.

How likely is it the case worker would accept my cover letter?

Following errors were made on my online application form:
1. Mistyped BRP expiry date - should be Oct-19, not Sep-19
2. Incorrect SOC - should be 2343, not 2345
3. Incorrect salary - should be 77k not 88k
4. Missed two travel dates outside UK after 11 Jan 2018 for my spouse application - but these are only 7 and 15 days respectively, and therefore still is within the threshold.

For the BRP - I have the actual BRP which they will scan presumably, and I have an employer letter which shows the correct SOC and Salary.

My biometric appt is scheduled this Friday at Croydon.

Does anyone have any experience that these errors can be mitigated through a cover letter, and how the cover letter should be positioned?

Thanks!

Just to add, its using the NEW online service, so I cannot amend anything by hand unfortunately, which is what previous posts seem to suggest.

Any feedback would be appreciated!

HI, how did you address this? I made an error too in my submitted form. Please advise!
