撕答案比撕书还痛心撒试卷比撕书还爽快
[sī dá àn bĭ sī shū hái tòng xīn sā shì juăn bĭ sī shū hái shuăng kuài]
The meaning here contrasts feelings - tearing up answers hurts more than tearing books because losing knowledge pains one's heart deeply while the destruction of examination papers (perhaps after frustration) brings some relief. This shows strong conflicting emotions about failure and tests.
