everyone is in the same boat...if the degree is what you really want to do then go for it! Nerves are completely normal , we are all having them. Anyone who says they dont have an ounce hit of nerves about starting uni is probably lying or just ridiculously confident and think they can alreadly plan how it will be and they will be the popular one in the first hour they arrive...ha!
dont worry tho...some people dont get the chance or opportunity to go to uni...we should take this opportunity we have and embrace it to the max!
