If you have followed first three weeks sincerely you must have got the confidence that this exam can be dealt with and cleared with systematic planning and understanding.
After 3 weeks of analysis, deep understanding of previous questions, making answer structure for PYQ, writing few answers everyday, revising and mugging up now u have fair idea about scope of upsc mains GS.
So its time to integrate this preparation with Essay paper.
Believe me, whatever you study, read, write and analyse for GS is sufficient to write great essays.
FOURTH WEEK
1. Continue PYQ answer writing, vision test paper question answer reading, making readymade intros conclusions flowcharts diagrams maps etc (and revising them) -> This should go on without fail.
2. Increase the number of GS answers written everyday to 12-13 (If u r confident start with timer, if u still need some time then write without time limit)
3. Now you should learn how to utilise the information you already know in multiple answers, single fact in various answers, a committee or its findings in answers, various reports, index (indices) etc in answers -> that is bringing authenticity to your answers via using credible sources (National & International level)
