Sorry five choose four . Hmmm , after asking seniors , I think 1200 is the best answer . Do you have any more seniors whom you can double check with ? But I think I'm quite sure now , seeing your reasoning and manutd's .

So kedah's answer is wrong .

There should be only six letters in a code .

OH oops. I didn't read properly then. Your answer should be right. Excuse me.

By the way , mingissms , do you still do Maths and Add Maths practices ? I'm trying to focus more on reading subjects currently . I find the act of researching about A lvl distracting me from my SPM studies , more excited about the subjects than SPM .

HAHA dude, I went through that during trials, because scholarship season was smack in the middle of my trials.

I still have yet to do past year papers for Add Maths and Maths, so I'll finish that. Maths and Add Maths is my way of relaxing anyway.

I've done most of my reading, I think. Need to brush up on experiments, moral and sejarah and maybe some bio closer to SPM, otherwise there's really nothing else. Guess it's just spamming past year and trial papers for me now.

Yeah , Biology , Sejarah ... Usual stuff . Anyway an essay question which requires flowchart to to be drawn to explain formation of pollen grains came out in my Gerak Gempur . Any thoughts about that ? Eight marks . In chemistry , cleansing action of soaps , eight marks also .

What thoughts should I have about pollen grains? Haha. My trials had soap come out too, but seven marks.

I can only come up with , at most 5 points for formation of pollen grains .

Sejarah workshop with a Guru Cermelang tomorrow! Anyways, soap came out in my trials(school paper) but it was 10 marks. Serious lack of points.

Cool your school is doing great job calling in teacher to give talks while my school........

Share stuff here , pretty please ?

Doesn't the flow chart count for marks as well? 5 points for elaboration and 3 for diagram?

Oh, by the way, do you have any tips on studying/answering biology? I find it tedious, even though I enjoy the subject.

How are you guys studying Sejarah now ? I really don't want to reread everything AGAIN it is energy consuming and ugh D:

Not like Biology. Easier to absorb in your brain

Hmmm . I think you're right .

What do you need , specifically ? Yeah I agree , biology sort of has KBKK questions which require odd answers , odd , as in , doesn't relate to the question . I really enjoy the subject too . As tedious as it gets , it's a whole lot better than sejarah . Whenever I read sejarah I get all agitated . Mehhh . I just finished bab 8. So many freaking dasar's! I think I've got to read those last few chapters many many more times . And all the cabaran's for wawasan 2020 ... It's hard to explain my frustration .

Oh, I don't know what I need specifically. Any help would be appreciated, particularly for paper 2.

Sejarah is HORRIBLE. Sometimes I can enjoy it, but trying to commit Bab 8 to memory is seriously painful.

is it weird that i enjoy sejarah more than biology?

i literally gave up on biology when i studied until nutrition and switched to sejarah instead. at least the sejarah questions were pretty 'dead' and always repeating. for bio, i thought the questions were unpredictable.

maybe because i seriously sucked at bio?

Dumb Question: for tabulation questions in paper three for all sciences, how do we know how many decimal points to put?

Not weird at all! Most of my friends switched to sejarah after being fed up about plants. Hahaha

Permutations of 6-letter code in which the letter U & E are side by side: P(6, U|E)

(1) Use 2 letters :: permutations of U|E :: 2!
UE
EU

(2) Use the remaining 4 letters :: order of 4 out of 5-letter alphabet: S|B|J|C|T :: 5P4
SBJC
SBJT
SBCJ
SBCT
SBTJ
SBTC
...

(3) Ways of arranging 4 out of 5-slot code where the inseparable 2-letter U|E is treated as 1 fixed slot and the order of the slots doesn't matter :: 5C4

U|E _ _ _ _
_ U|E _ _ _
_ _ U|E _ _
_ _ _ U|E _
_ _ _ _ U|E

P(6, U|E) = (permutations of U|E) × (order of 4 out of 5-letter alphabet: S|B|J|C|T) × (ways of arranging 4 out of 5-slot code)

P(6, U|E) = 2! × 5P4 × 5C4 = 1200 different permutations
