What should I do if I failed the computer test while applying for a Thai driving license but have a valid foreign license?

The user is seeking advice after failing the computer test while applying for a Thai driving license, despite holding a valid 15-year-old license from their home country. Comments suggest that a reciprocal agreement may allow conversion without testing, and obtaining an International Driving Permit (IDP) could facilitate the process. However, the user has already faced challenges with the test and is looking for solutions, including potentially hiring an agent or attending driving school for better preparation.
