If you fail in subject two, you can't evaluate it. When you make an appointment for subject 3, you should evaluate the previous subjects. If subject two fails, there will be no evaluation interface. No matter whether the subject 2 exam is qualified or not, you need to sign it. The signature of test scores is the confirmation of test scores and deduction items. Subject 2 can be taken up to 5 times, and each exam can be retaken once. If you fail the exam twice, you will be regarded as failing the exam.
