Hy,

To achieve a "double pass" in Plus One (11th grade) science, you generally need to meet the following requirements:

1. Pass Marks for Theory : Typically, you need to score at least 33% in the theory exam to pass.

2. Pass Marks for Practical : You also need to score at least 33% in the practical exams or lab work.

3. Aggregate Marks : Some boards might require a combined aggregate of 33% in both theory and practical components. This means you need to pass both sections separately.

4. Specific Board Requirements : Requirements can vary, so it’s essential to check the guidelines provided by your state education board or school.
