Is the BYU flats tongan test hard?
If you are planning on taking the Tongan Flats Test by BYU and are born and raised in America I suggest you STUDY! LOL.
Here is an outline of the test since its still fresh in my memory:

It is a 150 multiple choice test.

The first 50 questions is very simple. It is an audio recording of a man and a woman speaking in Tongan. They will say very simple phrases such as: "I went to the hospital because I was very sick. The nurse told me to take medicine because I have a high fever." Afterwards they will ask you questions and you have to select the answer that best fits the question.

The last 100 questions tests you on your grammar and reading comprehension.

The grammar section basically has you select the best word choice that fits in the blank. It gives you choices such as: a, e, 'e, o, ne, etc. The grammar section I believe is the hardest.

Reading comprehension uses scripture, folk tales and letters to quiz you on what you understood. The test that I took used 1 Corinthians 13, the legend of how Tongatapu was pulled out of the sea, etc. The first couple of paragraphs asks you questions in english. So it'll have the story in Tongan but the questions were in English. The last couple of stories had the stories in Tongan and the questions in Tongan as well.
