As expected, the paper 1 is a pretty conceptual paper. The trend has been there for quite some time but a number of prelim papers are not putting their focus on testing of conceptual understanding, but more on "killer" questions. (Same for H2 Physics)
Sharing my judgment
Paper 1
Q1: Partial Fractions, Inequalities
Q2: Applications of differentiation (tangent normal)
Q3: Transformations
Q4: APGP
Q5: Vectors (basics)
Q6: MI
Q7: Complex Num (no loci)
Q8: Maclaurin Series
Q9: Differential equations
Q10: Functions
Q11: Vectors (Line and Plane)
Paper 2, expected for Pure Maths
1. Complex Num (Loci)
2. Graphing Techniques, Curves (Hyperbolas, etc)
3. Integration and its applications (watch out for similar questions to 2015 P1 Q3)
4. Applications of differentiation (maximum minimum)
5. System of Linear Equations
Do tell me if I missed anything out. Thanks!!
I completely messed up this Paper 1 :(
Estimated 50+ marks
@ eagle, are you a teacher? Can i ask if there will be error carry forward marks?

Hi thomas! how are you doing! Yes there will be provided the examiner is observant enough (and different question have different ECF allowances)
Its okay, there is still paper 2.
Error carry forward also only applies for different parts within the same question. This is to prevent the double penalisation of answers for consequtive parts.

Thanks Fire521 for the response! I'm fine but worried for Chem P3 tomorrow. Unsure what they will test.
Hello! Was it considered a tougher paper?
How much would it be needed to get an A for H2 Math this year, based on this paper?

Are you a student? How did you find it? Haha.
Ya I am a student. I found it harder than most TYS past year papers...would 75 suffice for an A?

The probability of it happening is low for maths.

Most of my students did mention it's harder than previous years. On average, they mentioned they are unsure about 2 to 3 questions.
The best one was unsure of around 1.5 questions.
Hopefully they score well.
Oh no. I hope to get a B. Have to do well in Paper 2 :(
question 3 was a little bit unexpected and the cartesian equation of planes with perpendicular distance 12 away from p totally caught me off guard but the rest was fine i guess
If I get a 67 for paper 1, how much do I have to get for paper 2 to get an A or B?

Generally, it was a conceptual paper. Its not hard in terms of the prelim level standard hard. But because most schools prepared their students only for the "prelim hard" standard, students cannot solve conceptual questions.
If you all have not realised by now, the key to acing a levels is to study all the learning outcomes given in the syllabus one by one, a level examiners most usually set questions by learning outcomes for fairness (because they dont know what everyone else is teaching extra), so for chem math if you studied the outcomes and applied properly it should be manageable.
All in all, most of the questions were familiar (differential equations), its just how careful you are. There weren't any tricks actually in this paper, its just slightly more novel especially as some of you mentioned Q3. Q3 is actually interpretating the question " what does it mean when you transform one graph to something?"-some people thought (a,b) was (0,0) lol.
Besides Q3, the last vector question was probably tricky, but you could have either used what you learnt (dot product of normal to algebra the 12 perpendicular distance) or you could have found distance of plane p to origin and solved for the equations. Also depends if you are careful enough in converting equation to cartesian form.
but dont worry, A depends on many factors, including your luck, so work hard for the easier stats paper and try to score a 100.
Dear students,
Stay focused on P2 and excel even further!
Generally:
- there were a lot of arbitrary constants to cope with;
- substantial algebra work was required;
- intense feeling after one finishes the paper.
Kudos to all who sat!
Cheers,

Hey, I was wondering, wasn't system of linear equations tested in the last vectors question?
I don't think there's ECF for Math?
I found it pretty manageable. Surprised they tested every bit of vectors in this paper and there was a lot more focus on sequence and series than I expected. (I found Q6iii cool.) The only question I wasn't too sure about was Q4. Couldn't fully derive the formula accurately and ended up somewhat working backwards. Hopefully the examiner doesn't notice huehue. Also, after checking the solutions, I realized I stupidly screwed up inequalities HAHAHA of all question types LOL.
However, most of my friends found it difficult, especially question 3 (Transformation) and 8 (Maclaurin's). I felt that this paper had a lot of application and manipulation. Prelim questions are definitely harder... The toughness for prelim questions comes from finding the entrance to solving the question- then it's pretty much a straight route with some occassional twists and turns. This paper was more of a straight route to the entrance before being lost in a ladybrinth.

acerbicia, you are so acerbic!

Thanks.
@ThyWaffles System of linear equations refers to those questions that requires you to deal with a set of (usually, as in As) 3 or more equations with 3 or more unknowns. If we're given such a question, thank the heavens (or not, if you're hoping for a hard paper)- it's free marks.
Goodluck for Paper 2! :)
Hello guys, just a question when doing hypothesis testing, do you consider falling on the critical value as reject or not reject?
some schools teach reject, some schools teach dont reject
Oh My God! I hate math. :(
.
Yo any chance this year's B will be a mid 60? I ask my tutor he tell me standard B for A levels is High 60-mid 70 D: ?? I found P1 to be a very concept heavy paper but paper 2 was more or less standard questions ( excpet correlation ). Generally messed up paper 1 and smashed paper 2. So im hoping for a B but not sure what range it would lie within cus i know the standard deviation for B quite high but C also quite high sooooo... yeah idk
A very standard paper 2, but slightly more tedious and tricky.
For hypothesis testing, did you all manage to include 0 since mean age cannot be less than or equal to 0
