To Study is to read, memorize, learn information that you will need for a test/exam. To learn is the process of taking new information and understanding it and being able to recall it.

I've made corrections in your text: I'm overcome with emotion and I'm gonna thank you for all your thankful words about my email. Whenever I look for those lessons with the terms you taught us, I get choked up and remember all the moments I was with you. Thank you for the good news. It's awesome that you'll stay in the country two months more that I thought you would. Someday I'll meet you . By the way, Ma'soomeh and I will be classmates this term. Actually, she reminds me you. Because, apart from being a lovely friend, we were classmates when you were our teacher and it gives me good memories. (not sure what you mean here) I'm sending these two instrumental songs . I really love them .I thought I would send them to you .I hope you'll enjoy it!

A bird's eye view means seeing something like how a bird would see it flying. You see the entire picture of what's going on, not just a portion or snapshot of it. I have never heard of a "worm's eye view."
