学分计算器是一款可以帮助在校大学生计算学分与绩点的计算工具，它是由吾爱破解论坛网页分享提供的，学分绩点是以学分与绩点作为衡量学生学习的量与质的计算单位，使用本软件就能够根据你的课程学分和成绩计算出你的学分绩点。欢迎下载使用。
使用方法
国内大部分高校通用的计算方法是：绩点=分数/10-5，学分绩点=学分×绩点=学分×(分数/10-5)
每科的课程学分绩点=课程学分×课程权重系数×课程绩点
标准计算方法是将大学成绩的加权平均数乘以4，再除以100。比较常见的方法还有把各科成绩按等级乘以学分求和再以总学分除之。
程序说明
本程序基于.NET 4.0制作，可以计算课程学分以及达标所需学分
课程数据存于txt文件
types.txt用于存放课程类别，课程类别.txt用于存放各类别的课程数据，格式：课程名＋空格+学分(实验学分) tips：实验学分可空
