• Model Answer writing
• Topic Wise Notes

No new books at last minute preparations.

Answer Writing is Key

UPSC prioritizes quality over quantity when it comes to answer writing.

For answer writing:

• Understand the meaning of directive words (Discuss, Analyze, Evaluate, Critically Examine).
• Brief Introduction.
• Subheadings in the body.
• Inclusion of facts, examples, reports, diagrams/flowchart if relevant.
• Positive and Negative perspectives on any topic.
• Conclude with solutions and balance.

Integrate Current Affairs with Static Subjects

Study of current affairs shall not be done in isolation during the final period.

Rather:

• Connect newspaper issues with the syllabus.
• Revise important government policies.
• Go through key points in the Economic Survey. 
• Revise topics related to the budget.
• Prepare examples for Governance, Environment, Economy and International Relations.

This will make your answers more analytical and relevant.

Multiple Revisions

The final few weeks before the exam should concentrate primarily on revision.

A practical revision strategy is:

• Revision of one GS paper every 2-3 days.
• Daily revision of the optional subject. 
• Practice Essay writing every week. 
• Solve Ethics case studies.
• Revision of important facts, committees, articles of constitution and judgements.

Generally, experts suggest that it is better to strengthen prepared subjects than to take up new subjects in the final month.

Practice Mock Tests

Practice exams enable:

• Time management 
• Faster writing 
• Skills of presentation 
• Question comprehension 
• Increased confidence

After each exam:

• Check errors 
• Work on weak areas 
• Rewrite bad answers 
• Come up with models 

Effective analysis is more important than many tests.

Time Management While Taking an Exam

All papers require proper time management.

Some useful recommendations are:

• Allocate equal time to all questions 
• Don't waste time on tough questions 
• Leave room for graphs when needed 
• Write neatly 
• Answer all questions not skip some of them 

Completing the paper is more important than answering perfectly a few questions.

Avoid:

• Ignoring past year’s questions
• Memorizing without knowing the concept
• Poor handwriting and presentation
• Writing unrelated matter
• Taking too much time on one question
