Hello,

Your marks in chemistry and maths are excellent. In physics, if you do the following things then you can improve your score.

• learn and revise all the formulas of the chapter that you had prepared because in JEE main questions are coming directly formula based.
• Do session 1 question and learn from your mistake.
• Do prepare chapters like semiconductor, communication system , wave optics , electromagnetic waves, unit and dimension , mechanical property of matter, mechanical property of solid, modern physics. If more time is left then do remember the formula of current electricity and learnt to solve the circuit.
• You can include and exclude all the chapters of your own will
• Try to have your strong grip on at least 15 easy chapters so that you can get around 30 to 40 marks in physics in 10 to 15 days.
• Don't forget to revise the formula on daily basis also learn the application of the formula
• There are high chances that the difficulty level of the second attempt will be similar to the first one so do all the important concepts of session one.
• Complete at least one and one and half of the chapter everyday

If you belong to general category than there are very less chances that you will get CSE in any government college like NIT but if you belong to Delhi then you may get CSE in an suit and DTU.

No, your marks will not get added , you have to score again good marks to have good person tile no marks will get added in your further attempt.

Hope it help thank you
