Everyone has the different learning ability. Some can learn fast and the other only learn more slowly. If you cannot learn English fast, you must have patience because learning English sometimes needs your patience, or you will get nothing because you are too ambitious to learn so fast that nothing can be left in your brain.
Let’s learn English step by step from the beginning because you cannot jump to the highest level without going through the levels before. Please be patient because you will be there someday. In addition, your English will be the better if you know all of the levels.
