Staff Selection Commission – Combined Graduate Level Examination is referred to as SSC CGL. This examination is conducted annually to recruit personnel for various posts in ministries, departments and organizations of the Government of India. Graduate students looking for a government job opt for this exam the most. Since the number of students appearing for this examination is huge, therefore students work really hard to get through the examination.

Quantitative Aptitude is a very important section of this exam and has to be studied and prepared rigorously, without any scope for mistakes. Quantitative Aptitude is divided into two parts viz., Arithmetic and Advanced Mathematics. Here in this article, we are going to discuss important strategies, which will help you prepare Algebra and Trigonometry topics for SSC CGL exam. These topics are a part of Advanced Maths section.

First, we will be discussing the individual topics and then look at a common strategy to attempt them.

Tips to solve Algebra Questions

Algebra is a topic that can become very abstract at times. But in CGL exam, the level of questions is easy. Moreover, there are a few types of questions that are SSC’s favorite and appear a lot of times. So previous year papers can be of a huge help. Also, in algebra-based questions, hit and trial is considered as a good method to solve the questions. It is time effective and in turn, helps you to score good marks.

Topics to be covered in Algebra Section

A candidate should cover the following important topics of Algebra for the SSC CGL Exam:

  • Polynomials
  • Degree of Polynomial
  • Factorization of Polynomial
  • Factor theorem
  • Remainder Theorem
  • Quadratic Equations and its Roots
  • Nature of roots
  • Cubic equations
  • Maximum and minimum value of a Polynomial
  • Formula-based questions.

Tips to solve Trigonometry Questions

Trigonometry section often seems difficult to the students, but the real picture is quite different. All one needs is the basic understanding of angles, sides, formulas, and a good memory, because without these, trigonometry will be a hard nut to crack.

The trigonometry in SSC CGL is quite different from the core trigonometry that one usually studies in school. But in order to start the preparation of trigonometry topic, it is advisable to study from one’s 10th class mathematics book. This will help the students cover different questions of trigonometry and also provide a lot many questions to practice. The advice for studying trigonometry is different than that of Algebra. It is suggested to use smaller approaches like using options, value substitution and other tricks.

A student needs to understand that SSC CGL is an objective examination and the student is supposed to save as much time as possible while solving questions. One will not be rewarded for a longer method, what matters is the correct answer; hence one should learn methods that will help to find answers quickly and correctly.

Topics to be covered in Trigonometry:

Trigonometry can be broadly divided in two sections

  • Pure identity-based-

These include identities, angles, formulas, trigonometric ratios and maximum and minimum values of a function. It is important for a student to understand all the basics and learn them by heart. Once this step is done the student needs to practice as many questions as possible to understand how to apply these basics to the questions. And the last step would be to learn how to solve a question by substituting an angle (if possible) in a question to solve it. These steps will definitely help you to master this topic.

  • Application-based-

As the name suggests this part involves solving of questions from what has been learnt in the pure identity section of trigonometry. However, the formula that is majorly used throughout this section is  ; where P stands for perpendicular and B stands for base of a triangle in respect to the angle .

The various types of questions asked in this section are ladder slipping against a wall, moving towards/ away, from the pole, angle of elevation and depression, towers, shadows etc. These are comparatively easier and interesting to solve than the pure identity-based questions and there is always a question in the exam from this section.

Strategy to solve Algebra and Trigonometry based Questions:

  • Learn the basics/Formulas

Before starting with any topic make sure you know the basics first. For algebra you need to learn all the formulas and in case of trigonometry one should be thorough with all the identities and trigonometric values of the angles and the various formulas.

  • Know the various types of Questions asked from these topics

Once you are done with the basics, make sure you go through the different types of questions which are asked from these topics and learn how to apply the formulas/basics in them.

  • Learn the traditional methods

It is very important to know the traditional methods of solving questions in Algebra and Quantitative Aptitude. First, it helps you get a grip of the topic that you are studying. Secondly a person gains confidence and thirdly understanding short tricks becomes easy.

  • Short tricks

Students preparing for SSC are very keen on learning short tricks and most of the times, they don’t work on the basics of the topics instead cover most of their syllabus through short tricks.

Here the student needs to understand that although short-tricks come in handy during examination and helps in saving time, they aren’t the most effective way of solving a question; as not every question can be solved with a short trick. So, use short tricks only where important.

  • Solve previous year papers

As far as the trend in SSC in concerned the tier 1 exam is quite easy and the questions are mostly repeated from the previous years. Hence it would be a good idea to solve the previous year papers. Also tier 2 is slightly difficult and more number of questions of algebra and trigonometry are encountered. The papers will provide the right base.

  • Regular mock tests

Once you are done with the topic and have attempted the previous year papers, proceed to the mock tests. The mock tests are usually slightly difficult than the real exam and they will help you to prepare for the exam in a much better way and will also help you understand your weaknesses.
