Hi,

According to the Central Board of Secondary Education (CBSE) new rule, if a student fails in any one of the three elective subjects -- Science, Mathematics and Social Science), then the failed subject will be replaced by the 'Skill Subject (offered as a 6th additional subject).

According to new cbse pattern (you have to score 33/100 to pass as before) your term 1 & term 2 + practical marks will be added for your final numbers for marksheet. Then your final results will be sum of term 1 &2 and practical. So don't worry even if you fail in term 1 , you can do hardwork for term two. Because you don't have to pass each term individually. You have to pass in total of TERM-1&2 which you can easily do. And you know out 100 , 20 marks of practical , you just have to score 15 marks total in term 1&2 in theory paper to pass. But work hard you can score good , better than passing number.

Hope this helps.
