Two: For example, the 20 12 version of the five-year college entrance examination three-year simulation/new curriculum standard/science integration (version B), the new curriculum standard and the 20 12B version belong to the same book name, so there is no difference. The difference between the outline version and the outline version has been said above. The difference between version A and version B is that version B has more annual questions. I suggest you buy version B.
Third: Your third question is not a problem. You can only compare two different books, not the same book. If you insist on comparison, you can only say that it is equally appropriate. For example, your name is backstreet sky. Who is more handsome, backstreet or sky? Must be as handsome.
