Instruction in the classroom often lasts for only a few weeks. In most cases, you will only have a week or maybe just a long weekend to get up to speed. This is problematic in an area where the complexity of fresh knowledge is high. As a result, classroom instruction becomes less effective. However, you do not have to cram all of the material into a weekend when you use online classes. You can give the stuff back whenever it is convenient for you. This greatly enhances its usefulness in practical applications. The convenience of internet access by hiring someone to take my online course service means that you can learn while multitasking.
