Hello aspirant,
Law students have an advantage of logical and analytical approach over others. This will make Logical Reasoning and Analytical Ability sections easier.
Similarly, Indian Polity and Governance would be easier as they would have knowledge of constitutional law and related subjects.
However, law students must focus on sections that could be difficult, including basic numeracy, data interpretation, reading comprehension, languages, technology, economic development, etc.
they come from a legal background, they would already have a prior understanding of the subject. They can easily cover the syllabus and score high in the exam.
Aspirants should solve as many previous question papers and sample papers as possible to get familiarize with the exam pattern. This will also help them know the latest questioning trends, manage time better, and perform better.
They should also regularly analyze their performance in these mock tests to identify their weaknesses and strengths and work on getting better at weak areas.

The importance of reading newspapers, magazines, books, and novels in UPSC preparation cannot be emphasized enough. Aspirants must make reading the daily newspaper a habit.
They can choose newspapers like The Hindu, Economic Times, and The Indian Express to enhance their general knowledge and language skills.
Also, it's necessary for aspirants to practice writing every day as UPSC Mains would test their writing capability.
All the best.
