Chemistry Grade help

Ummm
actually i'm not sure what will happen when you don't take a component
But i think someone above said that we will got an U for that specific component
if you get an U in P1 but you do fine in other components
i guarantee your statement of results will not be affected because the percentage of P1 is small( In chem, bio, and others)
however (I'm talking about A level) you can see your score details in a piece of paper ( I really forget the name but such a paper does exist! I saw it myself...just ask this to your centre. I got( umm..actually only borrowed it for a while and returned it back) mine from my principals office. Because everybody doing test in my centre is listed in the paper I believe that each centre have such paper for each subject.
I got A in P1 math and I got C in S1 last may-june session and in the statement of results I  got A( because the percentage of p1 in math is 30% and S1 only 20%)

omg......
o my god...
i'm sorry everybody
it seems my conclusion is wrong
YOU WILL NOT GET "U" IF YOU DON'T ATTEND A COMPONENT
U indicates that the candidate has failed to reach standard required for either a pass at A /AS level/ AICE Half-Credit...
NO RESULT indicates that a result cannot be issued because of absence for the whole or part of examination in the syllabus or because of a decision not to issue a result for some other reason
PENDING indicates that a result cannot be issued at present but will follow in due course
that's what written in my AS statement result...
If you do a retake you must take p1,p2,p3 altogether ( this is if you take AS Level now)
or if now you do all 5 papers together, you must retake them all in the next session
so sorry everybody..i should've rechecked it first before i post anything
but what i wrote is true for people that receive U
