帮忙翻译一句英语！看看我这样翻译有没有语病！

若你是高中毕业想进大学的话，可以这样讲：
After having graduated from high school, I didn't get an ideal job and found out that my knowledge was rather limited. So I decided to go back to school to further my education.

若你是本科毕业想进研究院的话，可以这样讲：
After having completed my undergraduate studies, I didn't get an ideal job and found out that my knowledge was still limited. So I decided to go back to college/university to pursue a higher degree.

原文写得还算流畅，楼上提供的答案已经指出必须修正的两个地方，不过，还需要将句子分成完整的两句较为妥当。你说go back to college 给我的印象是你已经在大学/大专毕业了。若不是的话，用go back to school 更合适。
以上供参考。

After graduation from college, I find there is no a proper job for me. Therefore I decided to get furter education for a higher paying job.

首先应该是 After graduation from college（university）.. 的习惯用法
其次应该言简意赅
再次你句中的“I didn't get an idea job and find my knowledge limited”同时否定了两个方面 变成了“我没有找到理想的工作和没有发现我的知识有限”

After graduation,I didn't get an ideal job and found my knowledge limited,so I decided to go back to college for further study.
my 放在那里显得罗嗦，可以去掉
后面那个应该用found应该改为过去式，因为AND是连接两个对等的成分

After my graduation,I didn't get an idea（IDEAL） job and find my knowledge limited,so I decided to come（GO） back to college for further study.

i didn't find an ideal job after my graduation and recognized my knowledge is limited.So I decided to get back college for further studies.
