i got compartment in one subject cbse mathematics but now i want to change my stream to humanities plss help me i am not connected to any school.just need you help

Hello Prisha

As you have compartment in Mathematics and you wish to change your stream to Humanities you have 2 options from here on:

1. You could try to study and clear your compartment of Mathematics.

2. You can change your stream to Humanities but you will need to repeat from Class 11th so you will need 2 years from now to clear Class 12th.

My personal suggestion will be to choose Option 1. Trust me I have dealt with this feeling myself and wanted to choose Option 2 but I worked hard and cleared my exams. I was scared not only in Mathematics but Physics, Chemistry and even Computer Science.
At last, it's on you what you want to choose.

Thank You!

on which marks gujcet merit prepared?. can CBSE student compete after giving only gujcet with gbse student?

HELLO,

The GUJCET merit list is calculated by considering 60% of the marks obtained in Class 12 and 40% of the GUJCET score. CBSE students are also eligible to compete with GSEB students, as the merit list is prepared by combining the Class 12 scores with the GUJCET performance.

Merit Calculation:
  • The merit list is calculated by combining the scores from both class and the GUJCET exam
  • This means that both your performance in the class 12 board exams and the GUJCET exam are considered when determining your rank

CBSE Students and GUJCET:

  • CBSE students can appear for the GUJCET exam, even though they are not from the Gujrat Board
  • For CBSE students, the 60% weightage for class 12 marks will be based on their performance in Physics, Chemistry, and Mathematics in their class 12 board exams
  • The remaining 40% weightage will be given to their GUJCET score.

Hope this Helps!

Hello Aspirant,
