## FE Resources

The Academy has recently developed a series of interactive engineering contextualised resources for technician level courses. These were created following feedback from college lecturers on more mechanical and electrical principles.

These resources are free to use, but to demonstrate to funders their worth, we need to know who is using them. So please email us the courses, student numbers using them and the resources you have downloaded: contact Stylli Charalampous.
