Reasons Why---London

<p>Hey guys,
My sister is going to be a sophmore in college and she really has her heart set on studying abroad (London). My father is unsure of letting her go because he is not convinced that it will help her resume and such. My questions are:
- Can you guys help me with reasons on why studying abroad is a great thing to do in college and experience?
- If anyone has studied abroad in London before, could you please tell me if it is very expensive due to the US dollar vs. British pound?</p>

<p>Thanks guys!</p>
