I agree with the peeps opinions, trying to join in societies or organizations at the start of the second semester wouldn't harm. Just to make you feel better, you'll gain instant companions at the second semester. Why? Almost all of the members of each societies are already friends, and knowing that the second semester means fresh meats are coming, they will make you feel welcome to their society (Still depends on the environment and the nature of the society). Just a piece of advice, choose your society wisely. There are societies that are really political. Choose something that you think will benefit you and give you the right social needs. Good luck my friend
