Current GK is most important. it cover most of the part... the static GK is related to the current GK like if Konark Temple is in news for some reason. then it may ask some que related to Konark Temple

Static GK in CLAT covers about 20–25 marks. An easy way to do this is , as you read Current affairs , go for the full details . For example “World Braille Day on January 4”. This headline covers a lot of things . like

• Why it is on Jan 4?
• because Louis Braille was born on Jan 4 ,1809
• who is Louis Braille ?
• the man who invented Braille script . who became blind at the age of 3
• What is Braille script ?
• Writing in which things are written by raised dot so that blinds can read.

Studying like this may help covering a lot of static GK .

here are some important topics you should cover for Static GK

1. Basic Science
2. Inventions and Inventors
3. History

These are some topics to be covered . May be I am missing some topics . Give each topic 2 -3 days . It will be done within 2 months.

Hope this will help you.
