Exam Room 24/7 is a free trial exam and practice test website based on the structure of the high school graduation exam from 2025, created by a teacher. The teacher needs a place to assign tests for students to take and grade immediately, without manual grading or requiring students to create accounts. The site grades all three types of questions: multiple choice, true/false, and short answer. The scoring system follows Decision 764 of the Ministry of Education and Training. Main features: assign tests via link or QR code, set opening and closing times and the number of attempts allowed; basic cheating prevention (full-screen mode, counting tab exits); saving scores to Google Sheets; statistics on the correctness rate for each question and a list of students who have not submitted. The Mix Test page accepts Word files, generates multiple test codes, outputs printed tests, answer sheets, and QR codes for entry into the TNMaker grading app. There is a sample Word file for 10 subjects. Designed for high school teachers and students preparing for graduation exams. Operates on browsers, both mobile and desktop. Students only need to enter their name, class, and candidate number. A unique feature: Word files are generated directly on the machine, not uploaded to a server. There is a preview mode showing the location of each question in each test code to control errors. The source code is publicly available on GitHub.
