Below are the reviews that Cristina has written.
Serena is a lovely tutor.
Before my son start lessons with Serena he didn't like Math but now not just he loves it but he even win a Math competition at school.
He started to feel more confident just after a few sessions.
She is one of the most approachable people you will ever meet.
Is very hard to keep an 8 years old boy focused online but she did it.
Thank you Serena!
