Form presenter is very useful tool for the Google forms, one can create timed forms here. I have used it to create to knowledge tests within my teams and organization. Its super easy to setup and create timer and also you can create visually enhanced forms rather than just the normal google forms, also we can track the activity of the user while viewing the form which can be very useful to track the malpractices, these features I have admired about Form Presenter. Customer support is also good and it can easily be integrated with Google. Review collected by and hosted on G2.com.

There's not much to dislike about it, one thing can be added as screen viewing while user is attending it. Review collected by and hosted on G2.com.
