If you struggled with the Vectors or Maclaurin series questions in this paper, do not just review the solution. Return to your topical tutorials and solve 5–10 progressive problems on that exact sub-topic before attempting another prelim paper. Conclusion
To help you get the most out of your revision, let me know which area of the paper you are focusing on: Find P(more than 3 defectives) using Poisson(2)
papers and their solutions are available through several educational repositories. The exam typically consists of two papers, with Paper 1 focusing on Pure Mathematics and Paper 2 covering both Pure Mathematics and Statistics. Course Hero Paper 1 (Pure Mathematics) Topics Covered:
Do not review the paper linearly. Cluster your mistakes:
Mixed progression (AP+GP) word problem, or summation of ( r^2, r(r+1) ) etc.
