There are now many places that provide English proficiency test services, one of which is http://britishlifeskills.com. This ability test has many functions, among which are as standard if you want to apply for a visa. If you intend to live in the United Kingdom, you must exceed the minimum limit in order to apply for a visa, especially if you wish to continue your studies in the UK. Of course, to cross the limit, you must learn first. There is no miracle beyond the limit without learning.
Learning English is not difficult. The key is that you have to be diligent and not easily bored. Learning the language is easier when practiced every day, especially when having to practice speaking. You do not need to study for a long duration because too much material is remembered will make you difficult to understand.
We recommend learning in short duration, but more often. Although the material learned cannot be too much, but with repeated many times will make your brain respond well.
