PrepU is an adaptive, formative quizzing program. The questions have been calibrated for difficulty by students across the country, and each question is assigned a difficulty level. After giving the student an initial test to assess strength and weaknesses,the program provides tests that are right at that specific strudent’s level–neither too easy nor too hard. As the srtudent takes practice exams, he/she progresses and is provided with gradually increasing levels of difficulty, exactly in accord with that student’s progress. Extensive research and efficacy studies show that this is an ideal and highly efficient way to learn. The program provides an incredible amount of feedback on strenghts and weaknesses and you can monitor your progress against national scores. There are extensive dashboards for both the student and instructor, providing a wealth of information on progress and strengths and weaknesses.
