一、课程解决的主要问题
课程主要针对青少年三大类学习问题：不想学（缺乏学习动力）、不韧学（缺乏学习毅力）、不会学（缺乏学习方法），以及26项具体学习问题，让孩子掌握底层学习力，一生都受益：
1. 为什么明明上课时能听懂，一做题就不会？
2. 为什么反复复习，还是似懂非懂？
3. 为什么做不到举一反三，题目一变形，就蒙圈？
4. 眉毛胡子一把抓，只会大量刷题？
5. 不会的题始终突破不了，找不到原因？
6.跟不上老师的节奏，越落越多，越学越没兴趣，怎么办？
7.英语单词、数理化公式、古诗文，反复背还是记不牢，一考试就空白。
8.知识点容易混淆，张冠李戴，历史年代、人物事件、地理概念、生物分类……经常记混、记错。
9. 课堂听懂了，课后全忘光。
10. 背诵效率极低，耗时巨长。
11. 阅读记不住内容，读课文、题目读完就忘，抓不住重点，导致漏了已知条件或阅读理解得分低。
12.复习效率低，越学越没信心。
13. 上课容易走神、发呆，听不进重点。
14. 跟不上老师节奏，知识点漏听、大脑断片。
15.看似在学习，其实脑子空空，效率极低。
16. 写作业拖拉、磨蹭，半天写不完。
17. 粗心大意，看错题目、算错数、漏题。
18. 学习时总想玩手机、吃东西、胡思乱想。
19. 因为总出错、学不好，慢慢失去信心，甚至厌学。
20.做事没有条理，东一下西一下，即使制定学习计划也基本完不成。
21.也做过一些提高成绩的努力，最后无效，开始怀疑自己，甚至怀疑人生。
22.对于很难的题目，不敢尝试，习惯性放弃。
23. 害怕同学和老师笑话，不敢主动回答问题，也不敢主动问老师问题，每次考不好都特别沮丧。
24.没有学习方法，眉毛胡子一把抓。
25.每天要学的内容很多，不知道如何安排时间。
26.每天也付出很多时间学习，但效率很低。
