If there is a typo in the signature of the subject 1 exam, it will be noticed by the relevant person in charge or institution, and the typo of the signature will be corrected to ensure accuracy. In some cases, the typo on the signature may not have a substantial impact on the subject 1 exam or related matters. Especially if typos don't lead to misunderstanding or confusion about test scores or results.

However, if the typo in the signature causes others to question the identity, authentication or authenticity of the signature, it may need to be clarified or corrected. If typing errors make the information related to the signature unclear or inaccurate, it needs to be corrected or supplemented.
