General Science Preparation for DFCCIL 2022 Exam: Important Topics, Study Notes

Understand the Basic Concept First

General Science is considered a conceptual subject, hence, along with the facts and figures, you also need to grasp the concept of the topic for better understanding.

Analyze the Important Topics from the Previous Year Question Paper

Previous Year Question papers act as a guiding tool for identifying the important topics, difficulty level, and pattern of the exam. This also holds true for the General Science section, therefore, before studying anything else, candidates should first solve the previous year question paper for DFCCIL Exam.

Choose Relevant Study Material

Most of the time candidates do not follow specialized study material which is relevant to the syllabus of the exam. This eventually leads to the loss of the candidate’s time and effort. Hence, to prevent this, candidates must select the right study material which is pertinent to the exam syllabus especially the General Science section as the syllabus is quite vast.

Make Proper Study Notes

Good study notes will help you revise the important topics regularly as well as in the last phase of the exam. While making notes, make sure you cover the important topics and make the notes in the second reading not in the first reading as in the first readout, every detail seems noteworthy and important whereas, in the second readout, you will be able to differentiate between the important and unimportant topics.
