I want to travel abroad in the summer vacation of my sophomore year, but I don't want to go to cram school. Any better suggestions?

The summer vacation is so long that you can make a reasonable plan. For example, go to cram school first or study at home by yourself, and then find a suitable time to go out to relax and broaden your horizons. In this way, you can learn more without delaying your study. If you travel, you can go to Sichuan or Yunnan, where the scenery is very good.
