  dammit cjc jc1 mid yr in 2 weeks time...and i'm behind like hell...later do badly then kena retain...i take 4 h2 subjects summore....blardy h2maths..so much different from o level ... anyhow 2 wks b4 prelim slack slack also a1 a/e maths and pure phy and chem for o. now i think C for everything happy like bird liao.
  
  now jc so tough lor. first 3 months pon lessons like hell. now midyr die liao. scarly retain then mother father confirm du lan me....must start revising... alevels so different from o's.....grrr.....especially MATHS... i luv u h2 maths.... u are so easy to study...i understand everythign in ur damn syllabus...
  
  start revision also no use liao(for midyr). haiz. must start studying for promos immediately after midyr...then can hopefully take h3 econs .....so all future jc ppl...start revision from day one and pwn everyone in midyr...hahahahha

  And Organic Chemistry section is disaster.

  Organic Chem more or less I'm stable. PM me if you need help. Will try to answer.
  
  Maybe 2 sample questiona:
  1. 4 chemicals are labelled A, B, C and D.
  The chemicals are: ethane, ethene, ethanoic acid and ethanol.
  a) Write down experimental steps you would take to differentiate the chemicals from one another. [3]
  b) Explain why ethanoic acid reacts less vigorously with metals as compared to sulphuric acid with metals. [1]
  c) Ethanoic acid reacts with ethyl alcohol to form ethyl ethanoate.
  i) Draw the structural formula of ethyl alcohol and state if ethyl alcohol has an isomer. [2]
  ii) Name the byproduct of this reaction. [1]
  iii) Esterification is a process that can be reversed. Often, the byproduct is removed to force the completion of esterification in the desired direction. Why must the byproduct be removed? [2]
  iv) State a material that resembles ethyl ethanoate in terms of linkage. [1]
  
  2. Cycloalkanes are a particular group of alkanes whose carbon chain forms carbon rings.
  a) i) Suggest the general formula for this homologous series. [1]
  ii) Hence, state the first member of this homologous series. [1]
  b) Suggest the isomer for the cycloalkane cyclopentane. [1]
  c) Under what circumstances would I get pentane from the answer in (b)? [1]
  d) Pentane, like alkanes, can undergo substitution reaction. Write a balanced chemical equation to show the formation of chloropentane from pentane and any other chemicals required. Also state the conditions required for such a reaction to take place. [2]

  For me,
  
  it is still of unstable
  
  I am still involved in my school NDP Parade for this year...
  
  Lousy in Chemistry especially for the last few chapters
  
  Favourite subject: History, SS and Pure Geo(Humans)
  
  Now revising more on Physics.
  
  For History, maybe read more outside books by borrowing it from the NLB, perhaps it will help one to understand more.
  
  For SS, watch more of the news to know more about the current affairs and situation.

  I think we're somewhat in the same boat
