Here are a few options for a WordPress post_tag description for “選課” (Choosing Courses), each with a slightly different focus:

**Option 1 (General and Concise):**

* **Description:** 關於大學、高中或任何學校的選課相關資訊。包括課程、科目、選課流程、注意事項等。 (About course selection information for universities, high schools, or any school. Includes courses, subjects, course selection processes, and important notes.)

**Option 2 (Focus on Advice and Tips):**

* **Description:** 了解選課訣竅，規劃你的學業。這裡提供選課建議、評分、與如何避開地雷課的指南。 (Understand course selection tips and plan your studies. Here, we provide course selection advice, evaluations, and guides on how to avoid problematic courses.)

**Option 3 (Focus on University Level):**

* **Description:** 討論大學選課，包括必修、選修、學分、畢業規劃、教授評價等。 (Discussing university course selection, including required courses, electives, credits, graduation planning, professor evaluations, etc.)

**Option 4 (More comprehensive, includes related terms):**

* **Description:** 關於選課，包括課程查詢、排課、加退選、學分計算、課表安排、教授評價、排課策略等資訊。以及與選課相關的工具與資源連結。(Information about course selection, including course searching, scheduling, add/drop, credit calculation, timetable arrangement, professor evaluations, and scheduling strategies.

**Key considerations when choosing:**

* **Your blog’s focus:** Is your blog geared towards a specific level of education (high school, university)?
* **Target audience:** Who are you trying to reach? (Students? Parents?)
* **Keywords:** Consider words people might search for (選課技巧, 課程評價, 課表製作, etc.) and weave them naturally into the description.
* **Length:** Keep the description concise and easy to understand. WordPress search engines generally prefer a concise description.

To add the description in WordPress, you can usually find the “Description” field on the “Edit Tag” screen (when you’re modifying a post tag).
