Candidates who are going to appear for the exam would be looking for some useful advice and tips to score better in Natural Science Subject. Let's check the complete picture -

 

TGT Science paper consists of two-part which is of 200 Marks and includes 200 questions. Each question is of 1 Marks and involves (0.25)marks negative marking.

  • Part A includes 5 Sections, each section is of 20 marks - English Language, Hindi Language, Reasoning, Quantitative Aptitude, Reasoning, and General Awareness.
  • Part B includes 100 questions from Science (Physics, Chemistry and Biology) and Teaching Methodology

Although the syllabus of the Science is more vast than any other subject and it is quite difficult to cover each small story that is expected to be asked in the DSSSB TGT Science exam.

Tips to Prepare the Science for DSSSB TGT Science

Let us divide the Science section into different parts:

1. Physics

2. Chemistry

  • Students should make a timetable for regular studies and allot time to all the topics of the subject according to their understanding.
  • It is always considered wise to pick up those topics and chapters which carry high weightage.
  • Practice questions as much as you can, understanding the question is the first step towards solving it.
  • Candidates should make it a point to revise the entire syllabus several times before the exams to be thorough with each concept included in each topic. 

 Overall a few Strategies that the candidates can apply here:

  • Write down all the important points, formulas, equations etc, in the form of bullet points to aid in last-minute revision.
  • Form study groups to ensure the exchange of ideas and information.
  • Solve previous year's question papers to get a clear idea about the weightage given to each topic.
  • Try giving more importance to difficult topics if time permits, else the candidate must work on strengthening those topics that he finds easy.
  • Give as many mock tests as possible to get an idea of the amount of time that can be spent per topic or question.
  • Try remembering the shortcuts, especially in the case of physics formulae and chemical equations.
  • Understand the topics as far as possible and avoid memorizing everything as too much information may get jumbled up.
