Tutoring in your own home, at your own convenience
Today's schooling typically doesn't allow any room for individual learning, which means that students who don't suit the pace of the whole class can fall between the cracks. If students aren't achieving at the level they are capable of, their learning can stall, leading to boredom and frustration. Their confidence can suffer and they won't enjoy school as much as they should.
I can help. I offer personal tutoring in a range of subjects for NCEA and Cambridge International Exams, and can provide students with the skills and confidence they need to achieve their potential.
I'm based in Auckland and will come to your home at a time that suits you, for maximum convenience and maximum learning. Because the home is a familiar environment, it's where the student is the most comfortable – this is an important part of enjoying learning.

27 January 2021 (updated 3 Feb) – Present situation
Sorry, my schedule is now rather full, so I'm quite unlikely to be able to accept new students. However, I do have a waiting list which every so often I manage to whittle back a bit, so enquiries are still welcome.

23 January 2021 – Fact checking simple chemistry
I came across this story about a new design of hydrogen generation and storage device. One claim by the manufacturer rang my warning bells.
Lavo says ... that hydrogen is "inherently no more dangerous than other conventional fuels such as gasoline or natural gas," ...
That doesn't sound right at all, because hydrogen is explosive in air over a much wider range of concentration than most other gases. It's why the pop-test for hydrogen works (which a number of my students have discovered for themselves). So I looked up the values of the explosive limits of the three gases in air. Outside of these limits the gas might burn, but it won't explode.
- Gasoline: min 1.4%, max 7.6%
- Hydrogen: min 4%, max 75%
- Methane: min 4.4%, max 16.4%
Yep, hydrogen gas is inherently more dangerous than gasoline or methane.
PS. Hydrogen is also odorless and can burn with a colourless flame.
