When I was a young student, I was told by many Korean English teachers to view the questions first in English listening tests both when I'm taking the real test or just practicing because it increases the possibility probability of getting my answers correct. answering correctly.


And Now that I can learn English without Korean texts and get first-hand materials from native speakers, I've been just viewing ESL channels and reading things I'm interested in and I recently saw a completely different tip for English listening contrary to the previous tip one given by from my Korean teachers. 

The advice was not to It said to not view the questions until after I’ve finished listening to the audio, and as reading the questions first will not help me improve my English listening skills. What do you think? Should I keep on continue practicing my English listening in the same way, or should I adopt a this new tip? I'm really confused.

Notes: This was very good. The way the first sentence was structured was a little strange.  I would write:

“When I first started learning English, I was told by my Korean English teachers to read the questions before listening to their corresponding audio clip, as it increases the probability of answering correctly.”

If you think about it, both your Korean English teachers and the other advice are correct, but they help you in different ways. 

1. Reading the question first increases your chance of getting the correct answer, but makes you worse at comprehension because you are only going to be listening for the answer in the audio clip.
2. Listening before reading makes you better at comprehension, but you are more likely to get the wrong answer because you have to remember the entire passage.  In general it would be better to listen first when practicing, and read first when taking a test, right?
