Part A: Section 1 of the NSAA

You have 60 minutes to answer 40 questions. Because of this, Section 1 is the most time-pressured section of the NSAA. This section can test GCSE biology, chemistry, physics and maths. The questions can be quite difficult and it’s easy to get bogged down. However, it’s possible to rapidly improve if you prepare correctly.

You have 60 minutes to answer 40 questions.

Because of this, Section 1 is the most time-pressured section of the NSAA. This section can test GCSE biology, chemistry, physics and maths. The questions can be quite difficult and it’s easy to get bogged down. However, it’s possible to rapidly improve if you prepare correctly so it’s well worth spending time on it.

 

 

Choosing your sections

As part of section 1, you have to pick a section from biology, chemistry, physics.

In most cases it will be immediately obvious to you which section will suit you best. Generally, applicants for physical natural sciences will choose physics/maths whilst those for biological sciences will choose the biology and chemistry. However, like the natural sciences tripos, this is by no means a hard and fast rule – its extremely important that choose the section you want to do ahead of time so that you can focus your preparation accordingly.

If you’re unsure which to pick, review the content of each section and try out some questions so you can get a feel for the style and difficulty. This table shows what the general questions are like for each subject.

The available sections

Required: Mathematics

Choose one: Physics, Chemistry, Biology.

Each part has 20 multiple choice questions. There is no negative marking so you should attempt every question in both the maths section, and the part that you choose. Each question is worth one mark.

Maths is the only required section in the NSAA. Because of this, being confident with Maths is extremely important in the NSAA. We find that students improving their numerical and algebraic skills usually result in massive improvements in both their section 1 and 2 scores. Remember that maths in section 1 not only comes up in the maths questions but also in physics (manipulating equations and standard form) and chemistry (mass calculations). Thus, if you find yourself consistently running out of time in section 1, spending a few hours on brushing up your basic maths skills may do wonders for you.

Section 1A: Maths

NSAA Maths questions are designed to be time-draining – if you find yourself consistently not finishing, it might be worth leaving the maths (and probably physics) questions until the very end. Good students sometimes have a habit of making easy questions difficult; remember that section 1A is pitched at GCSE level so you are not expected to know or use calculus or advanced trigonometry in it.

These are the formulas you must know:

Other topics that you should be familiar with include Quadratic Formula and Completing the square. Even students studying A2 maths can struggle with these topics because sometimes they are glossed over at school.

Here’s an example of a maths question that you could see on the NSAA. This one is all about probability (you can find the answer here):

Section 1B: Physics

Physics Questions in the NSAA are challenging as they frequently require you to make leaps in logic and calculations. Thus, before you go any further, ensure you have a firm understanding of the major principles and are confident with commonly examined topics like Newtonian mechanics, electrical circuits and radioactive decay as you may not have covered these at school depending on the specification you did.

The majority of Physics questions require a fair bit of Maths – another reason to brush up on your Maths! Most questions require two step calculations. Here’s a worked example Physics question with two ways of answering the question;
