hello samraa!
i just seen ur post... u are complaining about ur vocab.. i just wanted to assure u that nobody is born einstien, you may improve your vocab by reading and absorbing as much as you can... and what are these articles in news papers? these are essays... so keep reading and writing and at the end of the year you will have improved vocab and writing style...best of luck
