Similar to fitness training or learning to play a musical instrument you need to make a commitment to practise regularly
I recommend that you complete one revision lesson + speaking appointment per week because you will also have three listening activities to complete within a month of your speaking appointment. You can do more lessons per week if you prefer a more intensive revision programme. I suggest you start with once a week for a few weeks and then build up to two but only if you have the time. It’s up to you. Your choice. That’s why I like the flexibility of this way of training. Similar to physical training, you can sprint or go at a steady pace. There might also be weeks when you’ll need to skip because of holidays, family or work commitments. No problem. But please try to listen to some of your MP3 audio files if you can’t attend a speaking appointment.
