BT Grader

Dedicated to the memory of my mother Bayadaa Tangad

BT Grader is a free bubble sheet grading software ( answer sheet scanner ) with free bubble sheet generator. There are many bubble sheet grading software and special hardware designed for grading bubble sheet in the market. Most of them are proprietary and requires scanned bubble sheet as input. In contrast, BT Grader is free and has ability scan and grade pictures of bubble sheet taken by camera and phone. Of course, scanned sheet is also acceptable. You does not need pricey special scanner. Just take pictures of answer sheets and receive the report in desired format. The software supports grading of multiple version answer sheets and also can run in offline mode on a stand alone computer, so you can keep your students score securely. BT Grader is listed on one of most popular software download site. Thank you for using BT Grader.
