1. Almost, depending on your work intention, you can go to Zhejiang University if you want to work in Jiangsu and Zhejiang, and Nankai if you want to work in Beijing and Tianjin.

2. The scores seem almost the same. You can check the retest scores over the years.

Tuition is the least important factor. Just find a good job, just a few months' salary. Don't be inclined because of the different tuition fees.
