Does it matter if consulting engineers write wrong answers in exams?

Yes The correctness of the answer depends on the correctness of all calculations and deductions. If there is an error in one step, the subsequent calculation results will also be affected. In the exam, if you find yourself writing in a wrong position when answering questions, you can cross out the wrong position, rewrite it in the right position, mark the revised position, and try your best to ensure that the revised answer is correct.
