Mathematics in the second day of junior high school must brush the motif.
Proper brushing is a good choice. After all, practice makes perfect, and you can also study the motif (the most basic). Generally, interrogative sentences are derived from motifs. This is a very good method. There is no way to start doing the problem. It is likely that you are not skilled enough. It's good for you to do more questions first, if it helps to adopt them.
