The only reason young people, adults and children are slow or abandon reading or give up studying, is that they fail to understand, the words used in the subject, they are reading or studying.
If you do not fully understand the text that you are studying, so search immediately after the word that you do not understand. Get the word cleared. Read the text again. If you still do not quite understand the text, there is another word that you do not understand. Find it. Clear it up. Continue so until the text is fully understood.
The importance of - immediately clearing of all the words and signs - in the subject you are studying - has unfortunately been overlooked or forgotten in today's modern education. Perhaps this is the reason, why too many teachers and too many students don't help each other clear up the words and signs, they do not understand.
Get all the words clarified, as difficult as it seems. It is worth the trouble. The rewards are high marks, more respect for yourself and from others and what is most important - full understanding of the text you are reading or studying.
