How to do the final moving questions in the senior high school entrance examination in mathematics? Also, why can't I always learn science, electricity and chemistry well? Ask for advice!
Electricity in physics is mainly to remember the relationship between voltage, current and resistance, and then it can be inferred slowly. Chemistry, remember the symbols (chemical formulas) of chemical elements, the distribution of electrons and chemical phenomena, and remember all the jingles given to you by the teacher. Then the book is the most important thing. Read it several times.
