While the published T-score is rounded up, rumor has it that in MOE's database, the actual T-score is stored up to 13 decimal places. A...

I got 260 and missed RI COP by 1 mark. Is it advisable for me to appeal to RI as I have many certificates？ Hi, I think you should if they accept your appeal (Maybe independent schools have no restrictions on who can appeal). Nobody knows the outcome of appeal but I'm 100% sure that the chance is 0%...

### Re: Appeal Secondary One Posting

### Re: Q&A - PSLE Math

Doesn't look like psle question. Anyway....PollutedS wrote:Hi everyone!

Why is (2/3x-2) - (1/ 2-3x) = (3/3x-2) [Note: They are all fractions]

Thank you!

(2/3x-2) + [1/-(2-3x)] = 2/3x-2 + 1/3x-2 = 3/3x-2

Might be MO kind but I'm not sure. Definitely not psle so no worries.
