Hello there,

As you have not mentioned ypur board of education in the question, so we are assuming you as a CBSE student. Now let me clear you that, to get good marks in CBSE 12th class, you need to work hard. Below I have listed some very imporatnt points to get a good score.

• Start from NCERT books, read them thoroughlly and solve exercise questions
• Make a proper time table of study, study daily for atleast 7-8 hours
• After completing NCERT, move to some other good books
• Solve previous year CBSE papers. This will helps ypu a lot

Also, I have listed some good books for the 12th class.

Physics : SL Arora, Pradeep's

Chemistry : Pradeep's

Maths : RD Sharma

Biology : NCERT, Trueman's

Hope it helps.
