Why study a personal interest course with Oxbridge?

Our entire mission objective is to change the world’s views of education and provide opportunities for everybody to learn regardless of their educational experiences and background.

Yes, education is essential for getting the most out of your career, but it’s also a way to feel more fulfilled in your personal life. For example, a mindfulness course can help you tackle the stresses of work more effectively, but it can also help you stop and better appreciate the things around you.

All of our courses are available through our award-winning learning platform. Industry experts put the content together specifically for us, so even though you’re learning for pleasure, that quality of learning will be extremely high.

This platform and all of your course materials are available 24 hours a day, so you can study when it suits you, just like you should when it comes to personal interest courses.

If you’d like more information about any of our courses or have any questions, please get in touch with one of our learning advisers.

How does studying a personal Interest course online work?

Your free time is precious, and as such, when you opt for a personal interest course, you should leave each study session feeling invigorated. That’s one of the reasons why an online approach complements this so well.

You have complete control over when and for how long you study, making the entire thing more fun rather than a burden to get through.

In addition, with 24-hour access and the ability to schedule one-to-ones with your personal tutor, you get so much more out of an online course compared to more traditional methods of study.

What are personal interest courses?

Personal interest courses are topics you study not necessarily to gain a qualification (although some of these courses are certified) but more to expand your knowledge, challenge yourself and help you take up a new hobby.

If there’s something you’ve always wanted to learn but never felt as though you had the time or even knew where to start, we have a range of interesting courses for you to sink your teeth into.

From genealogy to garden design, these varied courses are tailored to the bold and the curious.

Why study an online course for photography or design with Oxbridge?

At Oxbridge, our mission is to help every student who enrols with us succeed in gaining the qualifications they need to change their lives, fulfil their dreams, and land a job that makes them excited to wake up every morning.

In addition to having ambition and drive, you also need access to quality learning materials and a robust support system to succeed. The learning platform available through Oxbridge isn’t just excellent; it’s award-winning.

Not only that, our tutors are highly experienced in their respective fields and just as eager to see you succeed. You’ll get one-on-one time with them to ensure you have the highest chance of success.

Why not speak with one of our learning advisers to find out more?

What are the benefits of online photography or design courses?

There are numerous benefits to gaining a qualification through home study, but perhaps the most significant is the ability to learn at your own pace; you don’t have to worry about waiting for other students to reach your level of understanding before moving on to the next unit.

You can also schedule your learning around your personal preferences. For example, some of us take in information first thing in the morning, while others last thing at night. Or perhaps you have a full-time job or family responsibilities to navigate. Online study doesn’t require strict adherence to a timetable; you’re in complete control of the course and your future, which is precisely how it should be.

What is photojournalism?

When you hear the word journalist, people envision a news or magazine writer, but that’s not the only pathway into this exciting sector. Every article is brought to life by the images they use. As a photojournalist, you’ll get to the heart of a story and explain it in picture form to be used in print or online.

What is a design course?

Design courses vary in subject but aim to teach students everything they need to know to thrive in their chosen sector. They tend to delve into the history of your chosen topic and study the people and practices that have influenced the industry before teaching you skills that you can practice and become proficient in.

Courses Taught by Experts


Early Years

Beginning my career as an early years practitioner inspired me to step into the world of teaching. I have since elevated my skillset through a range of qualifications including L3 in Assessing Vocational Achievement, L3 in Education & Training and L4 in Internal Quality Assurance. I’m a big kid at heart; I love Disney movies and also dabble in photography.  



STEM and History of Art

Marine biology, jellyfish conservationist, hairdresser, fitness instructor… I have an eclectic backstory! Art is my passion and one of my proudest moments was achieving my Masters in Fine Art. I then requalified as an Art teacher to share my knowledge with my students. For most of my career, I’ve supported vulnerable students with additional needs such as SEMH and SEN.



Counselling and Psychology

I always knew that a career focused around helping people achieve their goals was perfect for me. That’s why I became a tutor. I love to see my student’s confidence flourish as they progress through their courses. It’s important to help them fit their learning goals around their personal commitments so they have the best chance of success! 

Kelly, tutor


Education and Childcare

My 30-year stride in education started with childminding, to working with pupils with Special Educational Needs and Disabilities. I then tutored in a national reading programme and went on to become a Higher-Level TA. I’m elated to say I graduated with a First-Class BA Honours Degree when I was 50 – living proof that it’s never too late to chase your dreams!



Health care

For 10+ years, my passion for helping learners develop and grow has driven my career as a teacher. To help me progress even further, I am currently studying to achieve the IQA award. I love reading and I’m a self-professed Harry Potter fan. Talk to me about all things history, rock music, tattoos and true crime podcasts.

What an amazing company!

I am currently taking a Skills in Business Level 3 Diploma and have been nothing but impressed with Oxbridge Home Learning so far. Throughout the signing up process, Hayley helped me extensively to get started and get the course materials through as quickly as possible. She wasn't just trying to sell the course to me like other places that I enquired about, Hayley was genuinely interested in my needs and how she could help that, whether that resulted in buying the course or not. The materials given are incredible, easy to follow chapters and just enough information to ensure that you can understand easily. The content itself is really interesting and is made even more easier for me by breaking the course down into little, manageable assessments instead of one big portfolio or exam. My tutor, Jade, has been brilliant in getting back to me so quickly, both with questions and marking. Feedback has been really relevant and helpful with a breakdown of grades achieved. So far I can honestly say, having signed up for a few other courses and being let down, this is the best course all round by far. Everywhere will have positive and negative reviews however I would definitely recommend this course and company to anyone who wishes to study and gain an extra qualification.
Absoutely outstanding college
trustpilot rating
Absoutely outstanding college! Always knew what to do even in times when everyone was so unsure. I am very grateful. I enrolled onto 5 GCSE's , I got my results through my tutors and i was over the moon with them. I have just re-enrolled onto 3 a-levels so i can persue my ambition to be a bio-medical scientist. Once again i was talked through every details of all 3 a-levels, loads of information given about how to and where to book exams and costs. This was even offered to be split payments for me too , and this is something i went with as i wont notice the fees so much monthly. Yes, i could have gone to college but college doesnt suit my needs at the moment. My tutor support on my GCSES was AMAZING, never left waiting for long for questions or for marking. Even when my tutor/s were on holiday there was someone there to cover and there is no half terms or 6 weeks summer holidays that you have to plan for. I had quite a few phone calls, mainly just to get clarity on a few units, and i had a few zoom calls which were great - so easy. Thank you Oxbridge and specifically my tutors, James, Ollie, Sarah and May. I hope to get you at a-level if possible. And thank you to my advisor for helping me out in every aspect. Love you guys.

I have just completed my Level 3 TA course and want to thank Jenny Tidmarsh for all her support and guidance. Her response to all my e-mails was super quick and she always gave positive and constructive advice. Doing an online course, and especially during this pandemic has been challenging to say the least. Jenny has been an absolute life saver, calming frazzled nerves and giving sound advice and encouragement every single time. She is truly the most amazing tutor I could have ever wished for during my journey. If I could have rated higher than 5 stars I would gladly do so.

from the very first call Oxbridge looked after me
trustpilot rating
I was really nervous about re-entering the world of learning, it had been a while and i was secure in my job but ultimately unhappy and felt i could do more. I had read lots of mixed reviews from lots of college and wasnt really sure of what to do, or what was eve the right course for me. All i want to say is that i really need not have been worried, right from the very first call Oxbridge looked after me, they gave me lots of finance options and i picked the one most suited to me. The course was explained in detail and the information was then sent to me so i could read it at my leisure. I asked for a call back and this happened on time (i work shifts so it needed to be at a convenient time) i wasnt bombarded wth calls like i was from a couple of other colleges. I had a few questions and these were anwered clearly and consisely, there was no pressure which was lovely. I enrolled, received my logins that day with clear instructions on what to do next, admittedly i didnt start straight away but i completed the course with the help of my tutors Carol and Sarah in less than 8 Months i rrally am delighted! My support was more than good, it was excellent, my questions were answered promptly and never with judgement, no matter how silly they may have been. My feedback was thorough and constructive and made me aware of areas i needed to improve upon, and using the online system improved my IT skills too. I also recently enrolled on their jobready package, this has really helped with re-writing my CV, with my new qualification and provided me with some really good interview knowledge and this package was free!! Oxbridge helped me to stay motivated, they helped me get the qualification i needed and wanted, the service was excellent from start to finish and the added extras throughout were so helpful. Thank you so much for all you have done for me and my family (we love our mugs too) I have just erolled on another course and i am very excited to start this to add to my portfolio of new qualifications. To anyone thinking of enrolling, my advice do it!!! but remember its like anything you have to do it to get the benefit of it. I did and i am so glad i did. Thank you all again for being so great, helpful and accomodating in some really dark times, you have provided me with everything i need to get the career i really want. Wishing you a Happy New Year!
Fantastic customer service
trustpilot rating
I am extremely interested in persuing a career within the Criminolgy sector. I saw a course advertised online which I thought would be ideal to help in furthering my education. However, when I enquired about it further, the gentleman on the phone advised me that this course would not be useful to me. This was because it was more of an detailed insight into forensics and not a pathway into University. I felt a bit deflated but I appreciated the fact that he was honest rather than take money from me for a course he knew wouldn't help me. To my surprise he stayed on the line and took time out to go through other potential options such as an HND and looking at public services. He then emailed me all the links and told me if I ever needed any further help to give him a call. This, I thought was excellent service despite my not enrolling. The gentleman's name was Travis and he truly is a fountain of knowledge. He's polite, professional, charming and a credit to Oxbridge! Thanks again Travis for giving me some hope, all the best.
