I enjoyed sharing my knowledge about some of the free resources that are available online to help people study English, Adam! I am sure you'll find them useful - especially if you do as I advised and revise the entire English language from the beginning! I do this every year in the 5 languages that I speak! For example, in Italian, which I have only recently learnt, I have been revising all of the grammar points in Italian round about every 3 months! And, I will continue to do this many more times, before I expect to feel secure about my knowledge of Italian grammar! I feel that the harder I work in Italian or Mandarin, or indeed any foreign language, the better and more quickly I'll be able to communicate with people who don't speak English! And, indeed, why should they, or indeed why should anybody? If you want to speak a language well, you have to start by putting the foundations of the pyramid in place, then build it up gradually, to fill all the holes! Then, you'll be successful!!
