Marriage visa London embassy

[smp17]

Hey

So two questions for those of you who have experience with the above -

1) Am I correct to assume that I should schedule the medical at least 6 working days before the interview, and expect my passport within seven working days after the interview (I am selecting the free courier service back to a local depot)?

2) My UK birth certificate is the long-form, full version however my fathers details are not included, only my mothers. Can I assume this will be fine?

Thanks so much in advance!
