Start with learning the surahs from Sura Duha to Sura Naas.
Then move on the the remaining of the last Juz.
Last 3 Juz
Once complete, your next target would be the last 3 Juz as well as common places in the Quran, like Ayat-ul-Kursi.
5 Juz, 10 Juz, 20 Juz, 30 Juz
Once you have completed the 3 Juz and common places, you will have enough self-confidence, inshaAllah, to continue in this incremental approach for the coming levels.
