Hello Aspirant,

See as per the evaluation criteria released by CBSE for class 12th results, the class 12th result will be evaluated with the following weightage :

40% of the marks will be based on the Class 12 internal tests like unit test, mid-term and pre-board examination and 60% weightage will be given on the basis of students’ performance in Class 11 and Class 10 final exams which is further divided to 30% for each class that are 11th and 10th.

Now not only the best score of subjects will be taken into consideration but the 30% of complete result of class 10th will be taken into consideration for class 12th result.
