Tutoring etiquette

[Bagamoyo1]

Trivial first world problem and all that.....but here goes. DS struggled with sciences in year 10 so has had tutoring for the past nearly 2 years. It started face-to-face, and has been via Skype since Covid. His tutor is lovely, she’s been flexible with times, really supportive, and it’s helped DS massively. He’s doing his GCSEs now, and his last science exam is next week.
I want to send his tutor flowers to say thank you. Should I send them next week, or after his results come through in August?

Next week.
You are grateful for how she has helped DS.
Flowers in August looks like payment for results.

Thank you, that’s what I’ll do.

Flowers now. Tell her his result when he gets it.

yes flowers now for sure, whatever the results youre sending as thanks for the support and time
