LEARN EXPRESSING OF WISH AND HOPE

Wish or Hope?

---

I am not still confused about when to use wish or hope. As far as i know, wish indicates negative meaning while hope indicates positive meaning. Is that right? for example,

1. I wish I could pass the exam.( which means I don't think I will pass the exam)

2. I hope Iwill pass the exam.( I think it is highlly likely for me to pass the exam)

what about the following examples. does it make sense to you?

I wish you to find good products. vs. I hope you to find good products.
Also, If possible, please let me know the structure using hope and wish.
Thanks in advance.
