LOST~~~

wats has happen to me...
I mess up all the calculation...
That made me fail in Basic Soil Mechanic and Science For Building~~~ :(
I hope it won;t affect me again in Measurement, Contract Act and Estimating :(
if it happen, i guess i should forget being a QS which required many calculating...
A small mistake could caused a huge loss....
I need to improved it but don't know how to solve my problem...

I also need a silent life in my life...
I need it to concentrate in my study...
I hope god able give me a chance to give me a silent life..
without being "disturbed" by "some one"....
I need it in order to improved my study...
