Short answer: Focus on understanding each task, responding appropriately and developing your English across all four communicative skills.
Rather than feeling like you need to fix everything at once, use your score for each skill to understand where you performed more strongly and where further preparation can help you most.
If you are planning to retake your PTE test, this direction can help you prepare with more focus.
There is no single skill, question type or shortcut that determines your score.
Stronger performance comes from understanding the test format, responding to the task and developing your underlying English proficiency across speaking, listening, reading and writing.
The aim is not to overthink each and every score. The aim is to use what you learn from your results calmly, practically and as part of a wider plan to keep building your English skills.
