Overview

For Tutors

Hard to advertise yourself and skills

Hard to coordinate schedules.

For Tutees & Parents

Tough and time consuming to find a helpful tutor that you can trust.

SOLUTION

An app that helps connect hardworking students with helpful, reliable tutors

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.
