To start practising along with learning the course, you will have to manage your time schedule correctly. Practising always makes us learn things in a better way and therefore it’s important to have practice hours in your everyday schedule. For eg: If you learn your course for supposedly 4 hours a day, then you should at least have 1 hour practise session about what you learnt that day.
You can search online to find out what type of designs are currently in demand inside the UI/UX market. It is best to start small, so that you become comfortable with the basics first. For eg: you can begin with designing round buttons, or combining two kinds of shapes together to form a meaningful output and then reuse similar elements to create a bigger picture.
