CHEMISTRY TEST!

Today, I had my chemistry test and that was so tough for me. T.T My lecturer said that the test will be rather easy but that was not! The paper contain 4 questions I almost took 25 mins for the 1st question and when the invigilators announced that there were only 3 mins left, I still not yet do my question 3. Lastly, I just simply did it. Haizzzzzzzzzz.
