The key point of your study is only scientific words…!!!!!!!!!!
From the first class it has been taught by the teacher that remember the physical picture correspond to the concept……like to learn about the alphabet ……you use physical pictures…..a for apple……b for bat…….c for cat…….d for dog and so on….and still you use the same..
If you loose the confidence on any subject it means clear that you don’t know the scientific words of that course/chapters……scientific words are important to understand the concept…..without these no one can understand the subject…….what are the scientific words…….these are similar to the name of your friends…..like you have many hundreds friends….50-60 friends in class and then sections and out side the school and colleges……when someone ask to you anything about your friend a physical picture you visualize in your mind ….means you know the height/skin color/about hair/about that he/she wear the glasses or not, where he/she lives, how he/she talks and many more things….in a similar way a scientific word will have a physical picture and some properties. You have to just remember those pictures and properties, units of the scientific words in any subject/course.
These scientific words are like force, momentum, energy, conduction, depletion region, transistor, Laser etc ……there is a big list of scientific words in a subject. These were just an examples in physics.
In a paragraph of a chapter you have seen scientific words just highlight to them or underline, make their picture information clear and you will see that when you will read other book also you will not face the any problem and now you will feel more confidence in to the subject.
