    You’ll have access to 1:1 support from your tutor. All NEC tutors are subject experts, with experience in supporting online learners.

    “I have taught for NEC since the late 1970s on maths, sciences and engineering courses and have also been a tutor for the Open University in technology. Each student has different goals and I aim to help everyone succeed. When students find themselves in difficulty with their course, I endeavour to show them clearly the way to reach the correct answer. I have a Bachelor’s degree in chemistry and engineering. I have conducted research in chemistry and engineering and have a PhD in the latter. I completed the adult teaching qualification Preparing to Teach in the Lifelong Learning Sector (now called Education and Training Level 3). I live in East Anglia.”
