Ielts exam The day before i went to Ielts exam. The result of exam was not important to me, only participating and become acquainted the process of Ielts exam. So, I bought a Red Bull because I wanted to experiment the effect of its. During the exam it really gave me positive energy, but I have to say it is harmful for body and if someone take it for a long time that means he or she is going step by step to death. I take it only one time in my life and never take it again.
