The problem RVision solves

• In recent times, the pandemic situation has brought major changes in the way educational
  institutions function. The need has come to conduct assessments online - and this need is here to
  stay. Many institutions that have tried to adapt existing online communication systems for
  conducting examinations, such attempts have eventually been a failure. The workarounds
  burden both the students taking these examinations and the faculty members that design the
  tests. Therefore we propose a system to automate the entire process using which assessment can
  be conducted online in an improved manner.

• There are many platforms (both paid and open source) that provide online assessment as service
  to various institutions. The functionality provided by these specialized online platforms is fixed
  and cannot be altered to the needs of the institution. Most of these platforms provide automatic
  scoring for MCQ and scoring based on the exact match of the student answer with answers
  present in an accepted answer set or if it is a numerical answer, a range check can be performed.
  However, the long subjective answers have to be manually evaluated by the faculty.

• We integrated a NLP based solution to target that problem. We also offer plagiarism check to ensure students don't just copy paste answers off the web.

• In a video game like environment, students are encouraged with tokens for their performance which they can collect and ultimately use to redeem a personalized gift from the institution. The tokens are handed out for evey accomplishment, submission, performance improvement and sustained performance providing additional motivation to score will in tests and submit assignments on time.

Challenges we ran into

• Implementation of Webhook for plagrisim feature was more difficult than we initially thought
• Database Schema Design and relational schema was lot tougher
• Automating the evaaluation process using NLP
• For the custom blockchain idea we had the polygon offered us a lot of flexibility so that we could Integrate the Polygon network reward (Automated Wallet creation,Automatic Reward transfer , etc...)
• Ran into version mismatches
