You'd better relax when you think reading is ineffective. Personally, don't always force yourself when you don't want to study, which will lead to a vicious circle. I have had such a period, which is very painful and understandable. I think the most important thing now is to slowly sum up the learning methods that suit you. It takes time and continuous summarization. If the method is proper, your self-confidence will be enhanced and your learning effect will be good. I think your foundation should be good. Since you are willing to surpass your deskmate, you should first know whether your deskmate has mastered new learning skills and methods, instead of wasting precious time because of impetuousness. Adjust your mentality, define your goals, put them into action, and you will succeed!
