Take the civil servant chalk test, but get a full refund.

Generally speaking, as long as you apply for a formal institution, the refund problem is not big, but it will take a long time (usually claiming to be in the process). Before signing up for payment, be sure to see whether the contract is a full refund or only a refund of tuition fees (some training will generate a lot of accommodation and meals in closed training in hotels), so pay attention to signing the contract. Generally speaking, the problem of refunding fees is not big, because the so-called civil service exam agreement class plays with probability, but they have already earned a lot of money for refunding fees.
