I am not sure how to practice. Should i practice after the complete tutorial or in bits.

Hi Harshit. I think everyone probably has different learning styles and you'll need to experiment to find out what works for you. I find it helpful to follow along with the videos closely in workspaces, stopping the video when necessary. I watch videos over a few times if I'm learning a complex concept. I also download the practice files if available or I'll copy my code into my text editor on my computer so I can work on the project locally. Then I go through the challenges again to make sure I understand what is being taught. Try different approaches to learning the material to find what works best for you.
