Thanks for all the suggestions, here's my opinion.

There is no official comment from the IELTS authorities on whether abbreviations like T/F/NG count as correct or not. Since candidates never see their results or feedback, it's difficult to judge based on their experience. Plus, there are people who claim these contractions worked and some who deny this.

Therefore, I think it's better than safe than sorry and write answers in full. This will work for sure.
