I would to know about using informal contractions in conversation. Can I use these contractions such as gona, wanna, gimme, gotta,...in IELTS, TOEFL,...?
What do you think about learning and using these contractions? Is this good or bad?
The site gives many colloquial contractions:https://netfiles.uiuc.edu/k-lee7/www.../collcontr.htm
I am confused if I should learn it or not.
I'd like to hear your advice and thoughts.
Thank for help.
