i was a f6 student at VI.erm..in my opinion,ada advantages ada disadvantages lor.jz depends on wat u wan =)
taking f6 -- its tough,really de .. work hard hard,results still so so .. unless u r really pandai n really work hard hard til blur la =) but it do save lotz $$ .. nt tat burdening .. bt bear in mind, its quite risky oso .. hw to say? erm.. my frens who were same batch wif me , we worked hard 2geta 4 stpm , but many of dem cant get into local uni .. especially if u r thking to get into science stream as me .. in my class, nt sombong la,only 5 out of 34 ppl can get into local uni (of coz,im 1 of da '5') so wat others who cant get into uni do? dey were forced to get back to private uni / college lor .. sum course even wan dem study from diploma level again ler .. in tis field, dey r wasting $$ n time .. pity dem .. appeal n appeal pun still cant get into local uni ..

all da best to u =)
