As predicted,I should hav guess I failed my chemistry.Sad thing I had a careless mistake and I realised that if I have not got that question wrong,I would have gotten the question correct.It is such a pity that such a mark can be so worthy.But as it says,life goes on and I realised that life is not a bed of roses,and if I do not face the failure,I doubt that I will ever coop in the future. But I am so grateful that I did not fail that badly.I hope that next semester I would do better:)
