Wa Alaikum Assalam Wa Rahmatullahi Wa Barakatuh Sister,
Dont worry about the test. Relax and take it easy.
Just try your best and leave the outcome to Allah, whatever the outcome will be trust that it will be good for you Insha'Allah.
It will be great if you pass but if you fail then know that it may be best for you to fail the test.
Ma'a Salama
