i think you should first ask youself if your result in maths or bio is acceptable?
or the worst?
if they are quite acceptable
but you still want to get A in hkcee
i suggest you can try extension classes
but i am sorry that i can not tell which is better
since i have not owned experience in participating in such classes
the only thing i can tell is : try your best to find more inf. about the classes
such as the teaching method, is that suit you?
if your ans. is :my results in such subjects are not good enough to get
even B
i recommend a private tutor instead
would you consider me?
i am a candidate in 2007hkcee(science)
that i thick i must remember the content i have learned
and i think your syllabus will be similar to mine:>
i enssure i can get A-Bin hkcee
moreover, i have owned experience in teaching a F.5 student maths
p.s. my position in my form :5
i have bio note for hkcee
(main points)
if you need any help, please send me e-mail
hope that help you!!!
