Edulastic is the best online tool for formative and summative assessment. Very reliable and easy to use.

Develop assessments for units, semesters, and the entire school year. A significant challenge emerged when I realized students were quickly bypassing the system's security to cheat. This suspicion arose after observing anomalously high scores during final exams. Upon consulting with IT support, they confirmed that the software was vulnerable to hacking, which enabled students to view the correct answers.

It is a customizable classroom assessment tool for teachers to provide more personalized tutoring to their students.

I think this Edulastic is easy to use, and provides assessment items that are relevant to real life.
