Thank you for your important question.
May Allah, Most High, reward you for your desire to increase in knowledge.
You should return to the verses that you skipped. It is not required to recite the Sura in its entirety and then return. (Shurunbulali, Maraqi al-Falah)
Recitation of the Quran during prayer should not be done quickly but rather slow and melodious.
The Prophet Muhammad (Allah bless him and give him peace) said:
“He is not one of us who does not make his voice beautiful with the Quran.” (Bukhari, al-Sahih)
