I scored 24 marks out of 80 in the theory and 19 marks in internal out of 20 will I pass the exam
You scored 24 out of 80 in theory and 19 out of 20 in internal, making a total of 43 out of 100. Most boards require at least 33 out of 100 to pass overall, which you have achieved. However, many boards also require a minimum of 26 or 27 marks in theory alone. Since you scored 24 in theory, you may not meet the theory cutoff.
