Question

帮我改个错句，谢谢各位英语大神了。。。句子如下

OK guys so listen up! If I wanna let someone teach me but needs to be charged I would have signed up for an auxiliary class instead of asking such a messed-up question in here!

Answer 1

needs改成need，主语是I
然后把would have signed up 改成would sign up，虚拟语气

Answer 2

这是一个口语句子。没有太大的错误。

Answer 3

中间有些我没看懂，大概意思是不是：各位听着！如果我想让某个人教教我(但是需要被管)，我会去找个辅导班而不是在这问这些废问题.
括号里我猜的，但是看句型，应该是needs错了。let someone teach me but need to be charged，need的主语应该是I，所以不要s。
