Bromine atoms valency 1 as it needs to gain an electron to complete its outermost shell
Hydrogen has a valency of 1 as it tends to lose an electron when it combines with other elements.

Don't worry
When you study hard & have a good mentality then without a doubt you will get A*
I didn't study that hard in the last 2 months and that is the main reason for my bad performance in the tests. :(
I have friends who were getting marks lower than me through all the year (when I was getting A* ,they were getting B's) but they studied so hard in the last 2 month and they have very little mistakes in each test
