我的任务
分享Builder的错误观点,帮我指正
我是标题dang.......
我想做一个考题系统,涉及小学1-6,中学1-3,高中1-3各个科目
还能按照难度等级(ABCD)划分,生成试卷.........
哎我是个没有什么文化的人,可是我需要一张高一年级的A级语文试卷,给邻居小孩测试..
??? 我应该怎么做呢,愁人啊.
思路一(这儿我觉得是一种大家都会去做的事!!)
我先上书店或者网上弄点高一语文资料,然后看看哪道题目难度什么的都合适,我就记录下来.
然后去买A4纸.然后把选好的题目打印出来.然后交给邻居.
邻居收到后觉得挺好啊.小陈很能干啊.过几天再给我孩子弄一个数学和英语的卷子呗...
(我勒个去的重复上次的操作)我在去找资料.......................累死人了......
然后化学,物理的..............
思路二(这算是Builder吗,凑合用把)
我本来就啥也不会文盲一个,你个破邻居还叫我出题目.靠.哎哎哎谁叫哥欠他1块钱没还呢!!!
算了帮他一把啦,
我给我的母校,校长打了个电话告诉了他我需要(高一年级的A级语文试卷)这样一张卷纸.
紧接着校长又给高一语文老师提了一个要求,叫他这张试卷.
高一语文老师那肯定牛逼啦.一个卷纸还不是手到擒来的.三两下就选好题目了(还不要查资料什么的).
然后高一语文老师把选好的题目信息,丢给负责打印的人,
负责打印的人就按照题目挨个打印到A4纸上..........
打印好了之后卷纸就制作成功了哈哈.负责打印的或者老师就可以直接把卷纸给我了.
我也就可以交差了.
...数理化同上打电话,专业的人做专业的事....
卷纸什么的都可以简单点,嘿嘿.哪位闲着的没事把上述思路实现了吧.
还有什么不足的也请不足,相互学习

请发表友善的回复…

不太明白楼主问什么啊 是整个网站建立的思路吗 要是卷子方面的 可以用下我们以前用的思路 就是弄个题库 100道选择 然后随机拿出来10个考试
还是不明白楼主问的是什么
