i am goimg to give Improvement exam next year in three subjects so i will have two different years marksheet will it cause any kind of problem in counselling or future

No, it won’t cause any problem in counselling or in your future if you’re giving improvement exams next year in three subjects and end up with marksheets from two different years. Many students appear for improvement exams and it’s completely valid. During counselling, you’ll just have to submit both your original and improvement marksheets, and the best marks out of both will be considered wherever applicable. Just make sure the improvement exams are from the same board and are properly recorded. Keep both marksheets safe and present them whenever required.
