Tips for Further Progress in PG prep

Hi everyone, Intern here,following I_anki deck for the past few months. Left with around 6k new cards. Also making new cards based on PYQs as I_anki covers PYQs till 2021. Was a bit late in starting GTs. Gave my first GT a week ago - Got 130 corrects. What can I add more to my current strategy to boost my prep? Or should I adopt a new strategy?
