=====================
一、preply
preply的上课形式有两种:一对一私教和2-6人小组上课
一对一授课:
上课内容取决于你的兴趣，提前跟老师发送你想上的内容，老师会根据他个人的经验和你的水平进行备课。
2-6人小组授课:
上课内容已经提前设置好了，根据小组课程页面选择你感兴趣的内容即可，课上老师会讲授内容，激励组内成员的互动，具体形式取决于老师，中间会给一些feedback。
小组授课价格会比一对一便宜一些，并且效果也不错，我建议可以与一对一授课混合进行使用，还能省一定的费用。
preply第一次订课通过我的邀请链接可以获得70%的优惠，直接注册是没有这个优惠的(当时我就不知道有这个优惠 )，并且试听课可以进行全额退款或者换成当前老师或另外老师的一个课时（ps: 你通过我的链接注册购买课时后，我也会获得部分课程折扣，介意请直接去官方注册，但是可能会没有70%的折扣）。

二、verbling
verbling只有一对一授课一种模式，与preply一样，可以提前发送信息跟老师进行沟通，第一次注册会获得免费30分钟试听课（相比于preply其实这个福利有点不起眼，半小时基本干不了啥），正常购买的话都是满一个小时一次。
=====================
题外话:preply和verbling都是平台，就像菜市场，只不过里面的菜基本都是过了检疫的菜，但顶级食材和低级食材肯定还是有差距的，里面的老师虽然经过他们验证，但天下没有免费的午餐，请根据你的需求选择合适的价位。有些老师会设置购买多个课时的优惠，但决定跟一位老师长期上课时请确保这个老师适合你，而不应该只看价格。
个人建议，备考重要的考试请尽可能选择15刀/课时以上的老师。本人备考ielts选择了一位18刀/课时的老师，相当专业负责。10刀作用的老师我也试过，但这个价格的老师每天课基本都是排满的，基本不会有太多为你备课的时间，练练口语还行，指望老师为你太个人定制化的备课可能不太现实。一分钱一分货，一切取决于个人选择，合适才是最好的。
=====================
ps: 附上个人verbling的统计数据，preply的统计数据好像没找到，懒得找了。
