Hi aspirant

hope you are doing absolutely fine

No, the weekly tests are not counted in the result of final examination of class 12th in GUJARAT boards .Basically, the unit tests of 12th standard are very important for the final exam. The criteria for this year, that is 2021 has been prescribed like the -

The GSEB Class 12 marking criteria will factor in the marks of Class 10 and Class 11, along with the unit test marks of Class 12.

A total of 50% weightage is for Class 10 marks, 25% for Class 11 marks and 25% for the first and second unit tests of Class 12.

here it is no where mentioned about weekly tests. And in no state board exams, weekly marks are included. For more, visit- https://www.careers360.com/keywords/gseb-general

ALL THE BEST
