S @ think is a free teaching tool, entirely in English, specifically created for teachers to generate knowledge questionnaires in order to evaluate their students.
S @ I think has no limit when adding questions, from a simple question up to 1000 (or whatever you want). The student has a predetermined time to correctly answer each of the questions.
When it comes to correcting it will be very comfortable, easy and fast for the teacher, because the whole process is automated and in a few seconds S @ think will inform you of which questions in the questionnaire have been answered correctly.
You can free download S@piens 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
