While studying biology, a student should have to read about all plants, and greens, baby plants. This is at the first time not easy to understand so the student would not be interested to study this subject. Once the student is assigned to answer biology answers he would regret to answer. At the same time, he contacts expert teachers; the expert teachers would provide answers for all the biology questions. Further the teachers would be providing brief description for all the questions. Once the student is going through everything he or she would be able to understand the subject.
Basically any question in any subject would be very difficult or difficult to understand. Once the tuition teacher explaining about the answer and the subject it would be very easy to understand, in future the same student would be in a good position to answer to the question. While studying the student would be doing plenty of things apart from his studies, a student must have to shine in music, dance, sports and other topics so the student will not be able to focus much on the studies this is the problem with the student. Apart from this travelling time to the school is additional time sucking, and the student will not be able to focus much on any subject, therefore the additional tuition is compulsory for all the students, in this tuition a student is now focusing on the particular subject, he or she is clearing all his doubts related to the subject, so the student is gaining more marks from the subject, at the final test or exam, the student will be able to get the better grade, than the previous exams.
A student once receives a book related to a school subject, it would be thick and it would contain many pages, even weight of the book will be heavy, while carrying the book, a student would be feeling he would not be able to study the subject, he would place the book corner of the cupboard he would never take the book, because it Is with heavy weight and with many pages. At the same time, an experienced teacher explains about the subject, he would feel the book is light weight and he would think now he could do that subject very well, this is psychological fear for all the students. However, class teacher cannot explain more about any subject, the teacher would be following the syllabus and going on the syllabus.
