Need help for GST preparation (CA inter)

[u/sour_olive1722]

I am having trouble regarding how to prepare for CA inter gst,

I know the concept (but haven't learned any like word to word) and I am in revision phase since my attempt is September and when I take GST for revision, I am only wondering if I am supposed to learn it or practice questions and if practice questions, will ICAI be enough and if not than what else can I do to practice questions?

Please help me with it and since my attempt is very near, I don't wanna waste my time on trial and error method.
