Hard to coordinate schedules.
For Tutees & Parents
Tough and time consuming to find a helpful tutor that you can trust.
SOLUTION

Problem
Team mission statement
Connecting helpful tutors with hardworking students
First task: One Time Tutor• Functionality: Tutee needs a one time tutor to clarify a concept
• Tutee searches for available tutor by rating, availability, and location
• For example, Natalia is stressed about not understanding recursion for an upcoming midterm, uses Tutera to get extra help to understand concept.
Second task: Long term tutor request• Functionality: Tutee needs a long term tutor for continually help
• Similar to one time tutor request process but added UIs to track progress and book future sessions
• For example, Leo needs help to understand concepts for remainder of the quarter, he uses Tutera to get multiple tutoring sessions to do well in the class.
Third task: Person recommends tutor to somebody else• Functionality: Tutee recommends tutor to somebody else
• Tutee reviews past session and recommend tutor to somebody else
• For example, Vincent really thought Valentina was a great math tutor he had for a past class he took. He knows his friend, Jen is now taking that class and could use outside help.

Suggested UI changes - Tutee•As tutee
• Recommend friend by posting to social media or a button

• On scheduling appointments, use X or grayed out for not available times for tutor
Suggested UI changes - Tutor•As tutor
• put in rate for tutees to see• Subjects and grades teaching (high school
level, college students, etc)• Describe what it means to rate a tutee
better, are they attentive, smart, late, etc?• If not free at specified time for new
request, give option to say schedule at another time
