Students always have last minute doubts before they sit for their examinations. Some of these doubts can be cleared, by reading the textbooks a little more or asking a teacher or family member who has knowhow in the subject. However, there are occasions when these avenues are not available. This is where online forums come in useful. There are many sites where academic issues on a variety of subjects are discussed. The students can log on to these sites and post their questions. Soon they will get a variety of answers from which they can choose the best one.
It is not necessary that one has to go to school or college for learning and acquiring knowledge. This is the era of the World Wide Web. There is plenty of information here on a variety of topics in disciplines like science, finance, law and literature, to name a few. Students can log on to a good site and absorb all the information they want. Leading law societies, National Geographic and aviation companies all have their own websites to disseminate information to readers. Such sources allow readers to acquire knowledge even outside the environs of the normal academic world.
