Question: how long does it take to get good at touch typing?
Answer: Practising 'little and often' (15 -30 minutes a day) works much better than an hour or more once a week. If you practise regularly and don't give up, you should be able to learn to touch type fluently in 2-3 months, maybe even less. A total of 10 – 15 hours of practice should get you touch typing slowly.
