Guide to Video Lessons
Practising between lessons is essential as you want to learn and progress in the lessons rather than just end up practising in the lessons!
If possible, try to have somewhere quiet to practise.
It is useful to practise little and often as this keeps things fresh in your mind. Practising for around 10-15 minutes each day if possible would be a good way to start, building up to around half-an-hour each day as you progress.
The more advanced you become, the more practice time is generally needed. You may well find you'll miss some days, which is fine. Perhaps then try to do a bit more the following day when practice time may suit you better.
The hardest parts should be practised the most.
Practise slowly, correct mistakes, stay focused and concentrate.
