It’s August now and I feel totally unprepared. I’m aiming for
L1R5 of 10 and below and is it too late?? I
take 8 subjects, EL, CL, Emath, Amath, Chem, Bio, Geog and Combined
Humans. Actually I’m pretty confident for my EL and CL but I
totally suck in Chem so planning to forsake it completely already.
Everyone mugging like siao since June le and I’m wondering if
starting now (Aug) is too late… When did you start revising for Os
and how did you do? 
To tell you the truth...you're too late you can still pass
depending on the moderation. For my batch it was too high. But I
also suffered a burnout cos i.started in Jan n closong in I studied
16 hours w slight breaks. However, some tips for you. Complete ur
TYS at least 4 times a C5 shd be no problem. All the best!
