What grades do you need to become an accountant?

The answer depends on where you want to work... in the United States, to work for the government as an accountant you need at least a bachelor's degree in the field. Many private firms want someone who has earned a master's degree in either accounting or auditing, or an MBA with a specialty in one or the other.

However, the important qualification for many positions is post-bachelor's: you must take and pass the examination to be a Certified Public Accountant. The certification is separate from the academic degree, and has its own qualifications to be met.
