Online maths and physics tutor
Helping students achieve their best grades
This year, I took 2 IB students, 7 A-level students and 11 GCSE students towards their final exams. I also helped a 13 year old pass his maths entrance exam for Shrewsbury School. It was a busy year.
Read the testimonials on this site to see some of the results they achieved.
Look around you. That ripple when you lift your coffee cup, the sunlight streaming in through the window, the annoying noise your neighbour makes when he revs his car in the morning. All these are examples of the phenomenon of waves.
The mathematics of waves is modelled by the trigonometric functions, the sine and the cosine functions. They can also be modelled using complex numbers. waves are periodic. This means that the movement repeats itself in time and space. There is a characteristic frequency which represents the number of waves passing a point per second. Then there is the period of the wave which is the time between successive peaks or troughs.
A very important principle of waves is the principle of superposition. As a wave passes, particles move about fixed positions in a predictable way. The distance of tte particle from the resting position is the displacement. When two waves pass each other, their displacements add and after the waves have passed, they are completely unaffected.
Waves transfer energy but do not involve the large scale movement of matter. Next time you see the moon reflected in water or the sound of lightning, remember you are seeing physics in action.

I’ve recently been tutoring a student who is taking this examination. It is very interesting and requires true problem-solving skills, something that A-level examinations have not been very good at. The format is of ten multiple choice questions and four longer questions. It covers the entire A-level syllabus but requires a great deal of intelligence to be able to spot neat methods to solve them. It is required to be taken by anyone applying for a mathematics based degree at Oxford or Cambridge.
It tests the student’s attention to detail, subject knowledge and flexibility in thinking. It is required for any student taking a scientific or mathematical degree. Problem-solving is at the heart of mathematics.
As an A-level mathematics tutor, I notice that a large number of students beginning their A-level studies have remarkably poor algebra skills. This hard core of students (usually boys) are unable to manipulate fractions, confidently rearrange formulae, work with negative numbers or perform the necessary basic skills to progress in the subject. They repeatedly ask the same questions and try to learn methods by rote because they don’t have the skills to do otherwise. Teaching them can be very frustrating because the same issues are revisited again and again and little progress can be made until they learn basic skills which should have been learned at GCSE.
I should add that this is a minority of students but nevertheless a significant minority. If you recognise yourself in this category, do yourself a big favour and learn to walk before you try to run. Mathematics is a hierarchical subject and progression is made on the basis of having mastered prior skills.
Most of these resources are free to use. If a link does not work, please let me know. I use them on a regular basis.
There are plenty of syllabus-specific resources available if you know where to look. These resources are designed by teachers in their spare time and are in some cases designed around a specific syllabus. They make learning fun and less of a chore. A student can find the resource that suits their own learning style. I use most of these resources in my own teaching, online and face to face. Some have video solutions, some have worked written solutions and some have topic notes.
www.bland.in has a great set of GCSE questions arranged by topic. They are written in the style of the Edexcel A syllabus but can be used for any syllabus. Higher and Foundation tiers. I use these a lot in my GCSE teaching.
www.m4ths.com is a set of questions arranged by topic. Some of the worksheets have answers but not all. These are very nice because you can really choose the precise topic that you want to revise.
www.mathsnetgcse.com is an interactive vocabulary list for GCSE. Point the cursor at a word and it shows you the meaning. It’s also great for A-level students who need to brush up on terminology.
www.desmos.com is a free web-based graphing website. It is easy to use and intuitive. Plot graphs of data for a science report, enter functions with variables, integrate or differentiate numerically and so on. It has all the standard scientific built in functions. I find it indispensable for my teaching.
www.math-aids.com has loads of mathematics worksheets, dynamically created, by topic. Math-Aids.Com is a free resource for teachers, parents, students, and home schoolers. The math worksheets are randomly and dynamically generated by our math worksheet generators. This allows you to make an unlimited number of printable math worksheets to your specifications instantly.
www.mathworksheetsland.com claims that it has the largest set of maths worksheets available on the internet. You can decide if this is true.
www.edexcel.com is the edexcel exam board home page for mathematics where you can download past papers, mark schemes and syllabi.
www.examsolutions.net is an amazing site which uses video as the main medium of communication. Instructional videos are arranged by topic. The creator of this website has designed an app for revising A-level maths by unit. The apps are reasonably priced at £1.99 each.
BBC Bitesize has tailored its web pages to the syllabus that you are studying. These are a set of revision exercises and quick tests. In recent years, the BBC has invested a lot of money in educational resources.
I find that a lot of A-level students go into their first year of A-level very poorly prepared for the hard work that is to come. They often lack the general background knowledge that is essential to make progression or to understand properly the new material that they are undertaking. I thoroughly recommend that they review their subject knowledge in GCSE. Try the higher level questions in the first resource I mention above (www.bland.in).
www.examsolutions.net is a great website that has AS and A-level instructional videos arranged by syllabus. All the A-level syllabuses are covered.
The graphing tool mentioned above is very useful as a learning tool. Of course, you can’t use a graphing calculator at A-level in the exam but it is great for helping to understand what is going on as you learn a topic. It is useful for example to visualise how many solutions there are to an equation in a given interval, how numerical solutions to equations work and so on.
There is an online edition of a mathematics A-level text book available here if you want to try a different text book to the one that you have been given. It is good to use a variety of resources to get used to the different ways that a question can be posed.
Solomon Press does a great range of worksheets, some of which you can download here.
If you can’t find all the exam papers and mark schemes that you are looking for (sometimes there are restrictions), try xtremepapers.com. I make no warranty as to copyright infringement and you access this website and download at your own risk.
How about broadening your knowledge and trying some mathematics competition papers? You can access some here.
If you want to read up on the history of mathematics, there is a great place to learn about all the famous faces such as Pythagoras, Euclid, Fibonacci, Gauss, Liebnitz, and so on. I really think that we need to know more about them.
Hyperphysics is a logically organised site where you can find the topic that you are interested in revising or learning about by viewing linked ‘mind map’ diagrams. All pages are cross-referenced so that if there is a term that you are unfamiliar with, you can simply click on it. There are diagrams, and many pages allow you to enter your own values into calculations to see the result. Diagrams are very clear and a lot of thought has been put into designing the site.
A large collection of animations is available here using java as the medium of animation. Your computer will prompt you to install Java if you do not already have the current version. These are very instructional and cover all topics at A-level. There are also associated videos to view on each topic.
A fantastic set of AS and A2 level worksheets are here. There are also answers. The questions are structured and generally quite short. They are very useful for testing your comprehension of a topic.
A site dedicated to AQA A-level Physics A is here. All the six units are covered including powerpoints, past questions, short questions and answers.
This site (A-level Physics Tutor) is very in-depth. There are youtube videos, course notes, worked examples, derivations of laws, and a list of books available to download.
GCSE.com has a useful glossary of terms.
BBC Bitesize has tailored its web pages to the syllabus that you are studying. These are a set of revision exercises and quick tests.
Khan Academy has its own recommended science links for GCSE here.
This resource has a very wide range of maths worksheets for all levels.

This is an interesting topic. Probably the best author who wove mathematics into his stories was Lewis Carroll. You will find an interesting article here.
The article, from the New Scientist, describes how Lewis Carroll’s story was in fact making fun of the new mathematics of the 19th century. Lewis Carroll whose real name was Charles Dodgson was a mathematician at Christ Church College, Oxford. He was a traditionalist and took a dislike to the strange new mathematics of for example, complex numbers and other rapidly developing areas of mathematics.
Here is an interesting article on a maths question many Australian High School students were complaining about. I think that the question is rather contrived and therefore I would have avoided setting it. It’s not totally impossible though. It relies on knowledge that the median is the middle line in the box plot so that the mean can be calculated. Now you also need to calculate the regression line gradient so that requires knowing a point on the graph. This point is therefore (22 – 0.525, 684/20) i.e. (mean of x, mean of y).
b is therefore 2.0864 and using a value of x = 19, we find that y = -10.6063 + 2.0864 x 19 = 29 chirps per minute (to the nearest whole number).

If you are looking at ways to improve your understanding of mathematics, I can recommend some resources.
https://www.savemyexams.co.uk/
I highly recommend this resource for mathematics revision. This is the site I use the most. There is much material available for free, including much syllabus-specific material on the new A-level. Many of the mark schemes are available for the subscription of £60 per year. It is regularly updated.
I am always impressed at the people who spend so much time creating such sites. They really do dedicate a lot of time to them.
Another great site is Physicsandmathstutor.com. It is free to use and has a host of GCSE and A-Levél material. Many students use this. You may also view my page where I list various resources here.
