BYJU'S Written test | Byju's

Written test is a unique feature in Byju's classes. The objective of the project was to enable the students to attend the exam seamlessly and to support results analytics. In the requirement gathering phase of the project, we evaluated different approaches that we could take for the students upload the answer sheets. Usage of constrained sheets was not possible due to logistical demands it'd need to fullfill.

For evaluation of the answer sheets, a third party platform called Assess-ed is used which has the ability for question-wise evaluation- tutors can evaluate responses of all students to a question together, which makes the evaluation process much faster. To facilitate question wise evaluation the exact area in the answer sheet an answer belongs has to be specified, and that'd have to be done by the student himself. There were debates on which approach to take:

To make the experience simplest for the students, approach 3 in which the student doesn't have to tag the answers was taken forward after discussions with the tutoring team and product team. Key screens from the Desktop Web flow is as follows:

The exam is scheduled for all students together on a specified time slot. Students can join the exam from the upcoming cards, as well as directly from notification

Trials & Improvements

The subjective test module had its trial runs with select grades. Few changes in the dev implementation such as keeping the banner with upload button sticky and increasing the click area for the select files button were done after that. To make sure that students read through the initial test instructions, the flow was redesigned with new diagrams.

The student has to go through all the 4 instructions to start the test.

The diagrams are designed for easy understanding even for the lower grade students.

The CTA to start the test is given in the fourth and last instruction.

The CTA to upload answer sheets and to view the instructions again are made available in the Questions view on scroll as well.
