Learn English – Is tricky a formal word

formal-languageformalityregistersynonyms

I am now writing a report which requires me to use formal, academic English…here's the question. I want to describe a task as more difficult, or more challenging than other ones. Can I use the word "tricky"?

If not, is there any other word other than "difficult" and "challenging"?
My first report in English, 🙂 Thanks

Tricky is not a formal word.

Some people will say that it is informal. Some people will say that it is ok to use it in informal and formal writing.

Difficult and challenging are more formal than is tricky.
