Engineer Test

Today,we have a big test that i s hard.
That test is engineer.
We have to recongnize the color of resistance and complete the project broad.
It is easy to recongnize the color of resistance,but complete the project board is not easy.
In the beginnin,I am very nervous .
If we do not accomplish the project board,we will get zero grade.
As soon as I get electric parts,I do my best to carry out it.
After a moment ,I finish it.
Then,I test it by connect it to charger.
Unfortunately, the LED does not shine.
My heart is very sad ,and the one thing I have to do is find the wrong part.
Time passes one second by second,and my feeling is more and more nervous.
I cant find what is wrong with the electric parts.
I have no choice but to change the electric parts one by one.
I am tired about this job.
When I change the electric the resistance,the LED shines.
Oh,yes
I can leave the class and go home.=口=
I do not get the zero.
