if i english exam pass ,i will buy Laptop computer

问题描述:

if i english exam pass ,i will buy Laptop computer
If my English exam get 70 points,I will buy Laptop computer.
这两句有错误吗

都差一点,二楼应是passes,三楼忘了a laptop computer.
正确应该是
If my english exam passes,I would buy a laptop computer.
If I got 70 points in my english exam,I would buy a laptop computer.
第二句应该是虚拟语气,用got和would.
顺便说一句:好久不弄英语了.
