METHODS
I normally teach in small groups of 45 students, however each student will be working on the areas he or she most needs at the time so students will not need to worry about "keeping up". I explain how to do each type of problem, and them leave the student to try some on their own for a few minutes. That way I will know that they have understood what I have said, and they will have a chance to get comfortable with each new method. Often I will have to fill gaps in their background knowledge before they can understand current topics. I like to think of these as "building blocks". Once I am satisfied that they have mastered each type of problem I set homework and move on to the next level or the next topic. Doing the homework is essential to retaining what has been learnt so that we don't have to go over the same material two weeks later. We can then "build" rather than "repair". I have a range of text books here, and I have written my own notes and practice material which I photocopy as required.
The first areas I usually work on are those being currently covered in the student's class so that they can return to their next class with more knowledge and confidence. To this end, students should bring with them their text books and exercise books from school where possible. Failing that they should write down the types of problems they are doing so that I can work out the areas being covered. They should also bring along two 1J8 exercise books.
Each lesson is normally for 2 hours. Very young students (up to year 8) or students wishing to try me out may book for 1 hour at a time.
The results of this systematic method, combined with conscientious homework, are normally spectacular (see below for results)

"My children really enjoy coming here"  David
"Hi Bill, just thought you might to know that Arran is in his last semester studying for a Bachelor Of Engineering Technology at Unitec. He has been getting great grades (A's) and has landed himself a great job at a civil engineering company at years end. Frances and I would like to thank you for the expert training and tuition to Arran which we believe was material in Arran's success."
"It has been many years since I had tackled any maths other than that required for everyday living. I approached Bill Porter three weeks before a Level 1 University Statistics paper. As I had struggled significantly with this paper, I told Bill that my aim was to obtain a C grade required to pass the paper. Bill utilised different approaches to teach concepts when I had difficulty grasping them. We also worked through old exam papers and ascertained the likely content of what would be in my exam.
Three weeks later, when I entered the exam room, I felt that I had a good chance of achieving the C grade I desired. Confirmation of my results for the statistics paper produced a B grade. I was extremely relieved and excited to have achieved this grade and acknowledge that without Bill's tuition, passing this paper would not have been possible.
Bills patience, knowledge and professionalism during my tuition were exemplary. I cannot thank Bill enough for helping me to achieve my goal and would highly recommend him to anyone requiring maths tuition at any level."

"My daughter did very
well in her end of year exams and I think she went into the exams feeling a lot
more confident and less stressed,
so the lessons were definitely money well spent." ( Name withheld at
student's request)
"My daughter really enjoyed her first session last week and was really impressed as she grasped a concept regarding the graphs which she hadn't managed to before. I think you hit the nail on the head with her shortcomings regarding decimals, she does seem to have a bit of a gap there."
