MarkSheet: answer sheet

Answer sheet app for bubble sheet (OMR) exams.
Easy scoring, supports multiple answers, sub-questions, and descriptive questions.

Since you can freely customize the number of questions and choices, you can create tailor-made answer sheets for any test format, from daily school quizzes and midterms to major exams like the SAT, ACT, AP Exams, GRE, GMAT, LSAT, MCAT, TOEFL, TOEIC, and IELTS, as well as professional licensing exams like the Bar Exam, NCLEX, CPA, and civil service exams.

Furthermore, once an answer sheet is created, you can use the "Duplicate" feature to reuse it as a template endlessly, making it perfect for practicing past papers by year or doing multiple passes of the same workbook or exam for repetitive learning.
