Rock-Climbing course for Ewha students

Every student should know how to overcome their emotional and intellectual limits by themselves. Rock-climbing would teach students how to use the ropes lopes, sling and safety belt. Also it would teach how to knot the lope rope variously and hold the feet and hands. Rock-climbing has a grading system so students also should know what their climbing type is; for example, Top Roping, Hang Dogging Red Point and so no on.

The university should offer a course on rock-climbing because there are both emotional and intellectual benefits for all students who participate. Students can feel a sense of accomplishment and develop thinking skills. Rock-climbing helps students to successfully finish their goals without giving up.

When you they entered university, you they thought you they would prepare for the PEET exam to be a Pharmaceutical Chemists. However, you they have heard about some students who failed and the difficulty of the subjects, so you they want to give up because you they think your their capacity is not enough to for PEET. However, the feeling that you they felt when you they did rock-climbing will give them courage and confidence so you they will challenge the exam.

"She will be able to think of solutions so she'll be able to solve problems quickly as well."

"She can solve problems quickly due to being able to think of solutions."

You/yourself/your -> Them/themself/their

You speak about 'students' and using 'themselves', so you use "them" or "their".

If you are writing a letter for students to read, then you can use "you, your, and yourself".

This really depends on who your audience will be. Who you want to write for and who is going to read it.
I don't know how to write restatements well too.ㅠㅠ
