It will also help raise test scores at least partially because they will be able to remember what they learned when it was something that they liked.

You are preparing for your interview, but you are not sure how to answer a potential question. Only asking your friend might not give you the best answer to the question. But if you ask multiple people that are in the same field as you, they might answer your question the best. When there is a decision to be made, it is always important to ask more than one individual for advice because it helps you know all the possible solutions, avoid bias, and learn from others' past experiences. These different opinions will assist you in making the best choice.
