QuickField is a very powerful tool for teaching, applicable to variety of courses and university programs. If you are an instructor, interested to evaluate QuickField for use in a class, you may qualify for free one-month evaluation of the QuickField Lite Edition license (on discretion of Tera Analysis Ltd).
If you are not an instructor in the educational organization, or your Lite Edition evaluation is not granted for any other reason - you may anyway qualify for other types of evaluation (including Professional Edition evaluation).
