Some Tips to Prepare for Science and Technology

This subject would be very easy to study for the candidates who choose science after the 10th standard. Go through NCERT once and move to reference books as soon as possible.

Keep in mind the paper for IAS prelims has been designed in such a way so that candidates for every stream can attempt. Therefore just go through the basics, a deep study is not required of this subject or in any subject.

Point One: NCERT

For those who are not from a technical background, read NCERT thoroughly. Make sure that you understand everything written in the NCERT and then only move on to read other scores.

Candidates from Humanities backgrounds can skip the portion of physics and chemistry because not many questions are asked on these topics. Focus more on biology and recent development in the science field.

Each candidate should be updated with recent discoveries and breakthroughs in the field of science and technology.

Point Two

Strengthen your foundation because it’s critical to have a firm grasp on the fundamental concepts of the topics covered in the syllabus. From Class VI to X, you can learn the fundamentals of the subject by reading NCERTs.

Previous Year Questions should be done because this subject is so broad, it’s important to stick to the syllabus when studying for the Science & Technology section. As a result, keep a copy of the syllabus in front of you at all times and check to see if the topic is covered.

Point Three

It has been observed that questions about current events are frequently asked in both the UPSC CS Prelims and Mains. As a result, make the most of editorials from the Hindu and the Indian Express.

Make a small note of the pointers for any recent scientific developments. It includes reports on disease spread and containment using scientific methods, medications, space exploration missions, artificial intelligence advancements, and so on.

Furthermore, due to the ever-changing advancements surrounding COVID crisis management, you should expect a lot of questions from Science & Technology this year. As a result, you should keep up with reports on vaccine testing as well as the virus’s spread around the world.

Point Four

Solve a large number of mock tests and sectional tests. You can practise the questions for the Prelims online.

Practice answering questions as much as possible before the mains, practise answering questions and have your answers evaluated by your mentors. In science and technology, it’s critical to use a diagram-based approach and to include factual information to make your answers more substantive.

Points to Cover

Government policies and announcements in the field of technology should be closely monitored. Any new developments or initiatives enlisted by the Ministry of Science and Technology should never be overlooked or ignored by aspirants.

Aspirants should be familiar with common technology and themes they encounter on a daily basis, such as GPRS, RFID, 4G, Bluetooth, Internet of Things, and so on.

Topics to Focus

Take note of the recent Nobel Laureate’s research fields, as well as Indian accomplishments in other important forums. Any new inventions or discoveries should also be researched. Questions on Graphene and Stem Cells, for example, were included in the exam because they related to recent Nobel Prize-winning research.

Because the UPSC tends to frame questions from here, one should be aware of ongoing research and new breakthroughs. Concentrate on chemistry, physics, and medicine to get the most out of your time.

Some More

When studying for the UPSC IAS exam, biology should be prioritised. According to recent trends, UPSC is focusing more on biology and the most recent developments in the medical and health fields. Although the UPSC is unpredictable, it is more important than Chemistry and Physics. One of the reasons for its significance is that it has ramifications in areas such as conservation, biodiversity, biotechnology, and the environment.

Aspirants will benefit more from an integrated prelims and mains preparation strategy because they will save time that can be used for answer writing practise.
