Hello Aysha Riaz
You can find all the text book here on online. Just view the shop above and click under text books where you will find everything you need to pass your Level 2 and Level 3. Or you can also get them on Amazon.
Just so you know, take it step by step. Breathe and focus on the first step only. This way you will stop your mind from troubling you with stuff that is not even real.
All the very best with your endeavours.
I hope this was useful for you.
