Activities can make you feel more apart of the whole studentship as well, as more fulfilled. As a student there are great opportunities to build on a skill or interest, as you undergo group activities.
Whether its book club, arts and crafts, cooking or whatever the activity you can be part of a team exercise and feel more fulfilled or amused as a result.
Interpersonally you can spend time to talk to other students outside the focused context of a lesson and have an opportunity to familiarize yourself / make friends. Definitely these classes or groups can give you developmental achievements, so you can look back on your group with appreciation of the fact you did something. Some of these institutions have alot of activities to pick from so there may more likely be a niche for everyone, and definitely chances to gain skills. For instance a computer class may give you hands on advanced learning that could help with future assignments or be satisfying for those with such an interest. Chess club is great for those up and coming chess champions. Or perhaps there may be other game groups such as the [insert university] football club 1-5 grade, gym group etc. Of course these groups are a great opportunity to do cardiovascular exercise and with company, if you win you have represented your study institution. This is rare. Who knows maybe there is a medal waiting for you.
