Senior Maths lecturer with 25 years of experience in further and higher education teaches maths at GCSE and maths and further maths at A Level.

Colin is a wonderful teacher as he not only makes lessons enjoyable to learn but is also really dedicated to ensuring that you understand the material that he teaches and helping you out on parts that you are stuck on as well so you don't fall behind.

I first met Colin when I arrived in the UK. Colin help me achieve the maths level I need to enter my degree at University, with specific focus on the Biology area. Colin has a personalised approach and always tries to adapt his teaching style to the needs off the tutees. Colin is confident in delivering tutoring sessions both face-to-face or online.

Colin is an amazing teacher who has received many nominations for teaching awards from the students that he has taught. He has a long-standing enthusiasm for his subject and has worked with a wide array of students with diverse learning needs. He is patient and helpful, keen for his students to gain a solid understanding and practice with confidence. He is extremely conscientious in his preparation of teaching materials, and thinks carefully about the intermediate stepping stones on the way to solving a problem. He is friendly and approachable, putting students at ease and good at making tutorial sessions fun and engaging. Having worked alongside him for many years and seen the positive impact he has had on others, I recommend him wholeheartedly.

Colin is an excellent tutor with a deep passion for mathematics. He was both my professor and the supervisor for my bachelor’s dissertation. His teaching methods are exceptional, with a remarkable ability to explain complex concepts in a clear and engaging manner. I highly recommend him as a teacher, as his enthusiasm and talent make learning both accessible and enjoyable.

Colin was a great tutor who helped my daughter really gain confidence in her maths. He was patient and professional. I would highly recommend Colin as a tutor to other parents.

Colin is Execellent lecturer and mentor. I was his student from 2012 to 2016 and he helped in my academic and non-academic studies. He is emotionally intelligent to help and support students to succeed in their learning journey.

His knowledge of mathematics to put to practice is amazing. He is an amazing teacher that one would want.

I recommend him 10000% for any STEM subject.

I have worked with Colin as a fellow lecturer for many years. He is an excellent teacher who has a remarkable ability to explain complex concepts to all if his students whatever their level.
This is why he has been nominated and won several teaching awards.
I therefore strongly recommend him to any prospective students in mathematics. He would serve you very well.

Dr. DeFreitas was my professor for my module on Numerical mathematics and my mentor for my final year group project module. I cannot recommend his teaching highly enough. He has an exceptional ability to break down complex concepts from the fundamental level, ensuring that we not only understand the mathematics involved but can also apply and extrapolate these concepts further. His teaching style fosters an environment of curiosity and independent research, encouraging us to take on challenges while providing guidance whenever we get stuck.

Dr. DeFreitas is incredibly generous with his time. He has spent countless hours outside of regular lecture times to help my fellow students and me grasp difficult concepts. His patience and dedication are evident as he uses various examples and methods to ensure we fully understand the material. He is approachable and engaging, creating a classroom atmosphere that not only sparks a love for learning but also makes students feel comfortable seeking clarification and help.

What sets Dr. DeFreitas apart is his genuine commitment to his students' success, both academically and professionally. He has ensured that our understanding of the subject was firm and also introduced us to potential applications so that we understand where the subject sits in mathematics in general and its potential uses in the professional world. He has gone out of his way to assist us in our career paths by organizing meetings with industry professionals, leveraging his network to provide us with valuable opportunities to get insights from experts working in the fields we are interested in. He tailors his tasks to the level of each student, encouraging us to challenge ourselves while offering the support we need to grow.

One of the most valuable lessons I learned from Dr. DeFreitas was how to conduct mathematical research. During our project, he provided a thorough introduction to the topic and gradually guided us into conducting our own research. He started by having us revisit and reproduce existing theorems, progressively allowing us to venture into our own calculations with the guidelines he set. This approach gave us the freedom to explore and learn while ensuring we had the support needed when encountering difficulties, making the experience both enriching and rewarding.

In summary, Dr. DeFreitas is not just a great educator but an inspiring mentor who genuinely cares about his students' learning and growth. His ability to teach complex concepts with clarity and his dedication to student success make him an exceptional professor whom I wholeheartedly recommend

Colin is an excellent enthusiastic tutor who loves his maths and physics. I had the pleasure of observing Colin teaching University students and his expertise and way of delivery made the subject interesting and kept the students engaged. This resulted in better outcomes for all his students .

Colin is an excellent tutor. He is patient and good at explaining things. He has a deep understanding of mathematics and a lot of teaching experience.

Colin really makes things clear and understandable. I learnt so much with him that I thought I would never really understand. He explains things in an uncomplicated way and I feel much more confident in maths now.

I have had excellent feedback from students over many years regarding Colin’s teaching. I was the module leader and after completing each module student are asked to give feedback about the teacher’s performance. For over 10 years students provided marks of 9 or 10 out of 10 for teaching and motivating.

It has been my pleasure to work with Mr Colin for the last 8 years in Mathematics’ department at HIC, University of Hertfordshire.

He is very conscientious and hard-working individual who has proved most useful within the department. His scope of work includes investigating methods of improving the efficiency of work of students understanding with his teaching style.

Through results, Colin has been able to direct HIC, University of Hertfordshire towards a scenario whereby we can set our own standards, in conjunction with any international and national students, thus producing a considerable strength of our department.
