From the interviews it is hard to say if one persona will be enough or not but for the sake of being brief enough I’ll go with the one primary persona that is based on one of the interview participants that is supported by the survey data.

Female 21 - Sophomore at Math Engineering
Thelma is an outgoing and ambitious person, she likes to meet with new people and she is a natural born leader. She loves to collect people to communities, create new connections between people. Now she is a sophomore and getting her lectures a little bit more seriously.
As an extrovert, she is usually the one that creates a new WhatsApp groups for a lecture to help each other. She always have the most phone numbers.
She enjoys listening the lectures but this year they started to get on the hard subjects. Now she thinks that just listening to lecturers is not gonna cut it. She is constantly looking for more content to support her grades and she usually likes to find lecture videos. She tries to take as much note as possible, yet it is not easy to keep up with all. Therefore she ends up organizing her notes after lectures and sometimes she took photos of them and share them with her friends.
Right now she is an active member of 7 WhatsApp, 2 Telegram groups and 2 Google Drive folders (most of them are started up by her). She is also tracking down some courses on Khan Academy and got enrolled a class on Coursera. She feels overwhelmed to organize all those messaging groups from different services, various material coming from all over and cloud services.
She has her laptop all the times to check on the lecture content, constantly using her phone to take photos of whiteboard and some medium size notebooks to take fast notes during the lectures.
