Thank you for your help.And I still have some questions waiting to be answerd.
Subjects such as physics and maths need a lot of logical thinking.When I activated these subjects,I could not feel the process of thinking.After several rounds of activation,I still did not feel I had got a better understanding of the context.
The condition is serious especially when I photoread a derivation.Without a conscious understanding of most of the concepts appearing in the derivation,how can I really apprehend it?
