The instruction can be routine and tedious. Students do not learn as quickly if the instruction is not interesting.In order to have sufficient back-up help you will need to get a Spanish-English and English-Spanish dictionary, which would help with the words that are not covered in the CD ROM lessons.
This type of learning is called immersion learning because the student is immersed in the language. Unless you apply what you learnt on a daily basis, you will never be able to master Spanish in the real sense. You will need to converse with someone on a regular basis in order to keep yourself up to date and in constant touch with the language.
The student has to function in the target language every single minute. This means that the student has to buy groceries and gas in the target language. First and foremost you could get some light reading material, i.e. fashion magazines, comics, joke books (anything that holds your interest) and read. Have a dictionary at hand for the words you do not understand.
Reading is one of the best and easiest ways to learn Spanish or any language, as a matter of fact. Reading gives you a good coverage of the language and helps you construct sentences correctly. As you progress in your level of understanding of Spanish, you can graduate to reading novels, newspapers, and other such materials that are more serious and will offer coverage on formal words and ways of communicating.
