Hi,I was wondering that since every year,cambridge sets a new variety of questions,is there any resource that are recommended to read up upon?Of course,that's after aquiring the basic knowledge of the H2 chemistry syllabus.:)(Like H3 stuff or unilevel understanding etc etc) Wih thanks for any relevant information!

Hi folks,do help me with this A level question if possible.:)
j89/p1/Q 16b
The para. equations of a curve are x=at,y=at^2,where 'a' is a constant.
The points P:(ap,ap^2) and Q:(aq,aq^2) lie on the curve.Find and simplify an expression in terms of p and q,for the gradient of the chord PQ.Deduce from your expression that the graduent of the tangent to the curve at P is 2p.
Apparently I can do both parts of the question seperately which is useless.
I have problems trying to find a suitable expression that can be used relevantly throughout the question.I appreciate all relevant help given and thank you all wholeheartedly.:)



Hey people...I'm a college student..Oh gosh this is the first time I'm hearing such a comment.In any case,this two years of college life will be very fast.
The rigour of A level curriculum is definitely much higher than that of polytechnics considering the amount of knowledge we are getting within this short 1 and a half years period.Be prepared to be learning really advanced stuff and having tests frequently.Not to mention having fun with the 'amazing' project work which...yeah,you'll be having fun with it....Together with your other subjects to study as well as cca.:)
My point here will be to consider your decision carefully as it is really not a child's play once you are there.Study,revise and homework are part of the everyday activities for most of us.
So yeah,for those of you who are willing to take up the challenge....Welcome aboard!To the life of muggers where we share our stress with each other,haha.
PS:Do read up on your own if you have the time.;)



10cm^3 of a solution containing 0.800mol.dm^3 of MnO4 ions were mixed with 10.0cm^3 of a 15.0moldm^3 solution of hydrogen peroxide.Calculate the volume of oxygen that will be liberated at s.t.p
A 16.5 cm^3 solution of acidified potassium dichromate of concentration 0.101moldm^3 is reacted with a solution containing Fe^2+.What volume of a 0.500moldm^3 concentration of Fe2+ solution will be required for a complete reaction?
Hmm...How do I go about these questiond and also on back titration and endometric titration?Thanks in advance.:)



Hey,maybe I can help a while.If you were to take combined science,certain JCs would only allow you to take one H2 science from your subject(.e.g.physics/chemistry,either H2 chem or H2 physics but not both).My college still have to give bridging programmes for students coming from combined science background.:)
H2 science aren't easy to start off without prior knowledge from pure sciences.But still,work hard and overcome everything.:)All the best for your Os.



Hey if anyone is on the look out for this shoe,adidas adizero adios 2,
do send me an email:[email protected]:)
Would appreciate if any kind souls will help me find that shoe,thanks.^_^



A cubic polynomial has equation given by y=ax^3 + bx^2 + cx + d.where a b c d are integers(the sign Z)
Find one such cubic polynomial whose graph passes through the points (1,1),(2,2) and (3,3).How many such cubic polynomials intersect the xaxis at exactly one point?
And also one more...
A factory manufactures three different designs of bracelets,A,B and C.Bracelet A is made up of 4 white beads and 4 pink beads,bracelet B is made up of 6 white beads and 3 pink beads while bracelet C is made up of 3 white beads and 4 pink beads.A total of 70 white beads and 52 pink beads are used per day.How many bracelets of each design can be made per day?
Really need help on these questions as I have a test next week.I'll appreciate any relavant help given.Thanks!:)



Hey guys.First of all,my results are none of the best.
English 5,CH(geog) 6,CS(phy/chem) 2,Bio 5,E math 1,A math 2,CL 4.
L1R4:16(A/B),14(C/D),L1R5:20
Planning on taking up either business(accountancy) or math in uni.
Enrolling in IJC science stream with this combi.:ECMP(my second choice is YJC PCME)
What are your viewpoints?
Well I can't enroll in spectacular JCs but at least the roof will really not fall on me.;)
I'm happy with my results though.:)
