I'm also the second book of grade one. I'm from Zhejiang, and I'm from Wenzhou Experimental Middle School. Science is between 95- 100 and mathematics is between 90- 100. In fact, it is very difficult to mention mathematics at once. Only by relying on sea tactics and practicing more can we master the subject thoroughly and improve our grades. Science, go to the bookstore to see everything about middle school science (the best teacher is the one you are interested in), and watch TV is also good. Our science teacher can let us watch Into Science and Animal World. I am more interested in biology. Of course, the most important thing is to listen carefully to every word and sentence in class, so that your grades will improve quickly. It's a bit bitter to memorize all your class notes, but it's gratifying to see that you have achieved such good results.
