Ok so here are the pics as i said. You may calculate the marks now Hope for the best

P.s : I have no share in compiling these questions and the answers. All credit goes to my Maths teachers who uploaded it. I'm only posting it here again, thought it might help many.

Just a couple of answers are wrong. I'll refer to those in the comments.

Answer to ques 3 is 1.15 rad.

Correct answer for bionomial expansion is
0.5+(5/12)x+(41/72)x^2

Also i think in the complex number, the real and img parts are interchanged. Please confirm whether im right or not.

 

[Shadow]

That's it. Rest of the answers are correct.

Hmm 7 ii my answer differs

I think I got 66/75. I got 90% at AS. Assuming I do great in S2 next week, do you think it's likely I get an A*?

Answer to question 3 seems wrong it was a decimal number which you had to write to 3SF

Don't really know how the threshold for A* works, but i guess you will be able to get a star if your S2 goes 45+.

Ok so here are the pics as i said. You may calculate the marks now Hope for the best do you think they will give marks if the methods are partially correct? say, if i get the normal vector wrong, will they give mark for the method of the equation at least?
