To help you meet the 60-65% criteria, let's break it down:

Current Scores

1. *Total 1st Year Marks*: 470

2. *Your 1st Year Score*: 253

3. *MPC (Maths, Physics, Chemistry) Marks*: 270

4. *Your MPC Score*: 142

Required Scores for 60-65% Overall

To achieve 60-65% overall, you'll need to score between 564 and 611 marks (out of 940) for both years combined.

2nd Year Scores Needed

Assuming you want to reach the higher end of the range (65%), let's calculate the required 2nd year scores:

1. *Total Marks Needed for 65%*: 611

2. *Marks Already Secured in 1st Year*: 253

3. *Marks Needed in 2nd Year*: 358

MPC Scores Needed in 2nd Year

To meet the 60-65% criteria in MPC, you'll need to score significantly higher in Maths, Physics, and Chemistry.

Assuming you want to reach 60-65% in MPC:

1. *Total MPC Marks Needed for 60-65%*: 486-526 (out of 810)

2. *MPC Marks Already Secured in 1st Year*: 142

3. *MPC Marks Needed in 2nd Year*: 344-384

Subject-Wise Scores Needed

To give you a better idea, here are some approximate subject-wise scores needed in the 2nd year:

- *Maths*: 120-140

- *Physics*: 110-130

- *Chemistry*: 110-130

Keep in mind that these are rough estimates and may vary depending on the specific exam pattern and marking scheme.

Conclusion

To meet the 60-65% criteria, you'll need to score around 358 marks in the 2nd year, with a significant improvement in Maths, Physics, and Chemistry. Focus on consistent effort and targeted studying to achieve your goal.
