A question!

[Marsha Lin]

Is the word "substantial" too big?
Is the sentence "My school life is very substantial." right?
Can someone show me how to revise it? Thanks a lot!

Substantial normally refers to actual physical size, or to a countable quality:

"I ate a substantial meal last night."
"He owes a substantial sum of money to his brother."

I don't see how you can relate it to your school life. What do you mean? Your school life is very hard? Very demanding? Busy? Difficult?

I mean I really enjoy my school life and I learn a lot of things.Not difficult!
Isn't it OK ?

I would suggest "My school life is very fulfilling". There isn't really one single word that would sum up both something you enjoy, but where you also learn. "Enjoyable" and "educational" are the two basic words, but I think "fulfilling" would be a good compromise.
