When I was almost 1 year old - в ед. числе. В этом же предложении, если уж "мои родители говоряТ", тогда "My parents say". Далее, здесь же, не думаю что надо использовать продолженное.
либо так если используем when,
My parents say that when I was almost 1 year old when they gave me pencils and paper for drawing,
I was banging rhytm of the music which I heard lately.
либо так, если не используем:
My parents say that when I was almost 1 year old they gave me pencils and paper for drawing but I banged rhytm of the music which I heard lately.
Because of it - лучше That's why.
I like it because I can do it very well anyway my teachers say it. Это лучше разделить на 2: I like it because I can do it very well. At least my teachers say it.

Ещё подумаю, наверняка не всё))

Dear Finley

How are you? I'm so sorry to hear about your grandmother. I hope she will get well soon!

Thanks for inviting me to the cinema. Unfortunately, I'm afraid I won't go, because I really need to prepare for my math exam.

Anyways, maybe we can go to karaoke next week?

Also, lately I was reading a very interesting book and I wanted to recommend it to you. It's called "Call me by your name". This book is about two people, who suddenly fell in love with each other in Italy.

Hope to hear from you soon.

Love, Caitlin

как-то так

удачи!
