Generally , languages need a long time to accumulate experience and familiarity. Hence the longer you practice the language the stronger it will be.
One of the methods you can use to practice languages is by having a weekly reading target time depending on your overall timetable. In addition, you can do a minimum of 2 writings every week and try to get them marked. Apart from doing 2 writings , one can also do 1-2 weekly compositions and have 2-3 hours of weekly conversation practice to sharpen their language skills. These tips will allow you to efficiently master any language one studies for.
