Generally, the more practise you do , the quicker and further you will progress. Other important factors include age and ability as well as how and what you practise.
A beginner will need to get used to holding the strings down and may only be able to practise for 10 minutes at a time. As your fingers become tougher and stronger you will be able to play for longer periods, so to start with practising a little and often will usually achieve better results than practising for one long session each week.
A student working towards Grade 1 may need to practise for 20 minutes a day, whereas a student aiming to pass Grade 8 may need to practise for more than an hour.
A good practise routine does not necessarily mean that you practise the same things each time. Greater progress is often made, especially as you become more advanced, by spending some sessions focussing mainly on one aspect of your playing and some sessions concentrating on other areas.
It may be that you are trying to master a piece but need to develop a particular technique in order to play the piece fluently, or you can play most of the piece but need to focus more on a particular section.
A practise routine that works for one student may not work for another. The important thing is to establish a routine that works for you and to learn at a pace that you are comfortable with.
