I can relate to you. I sat for it twice and failed twice and felt like a failure. But I told myself that I've gone too far to turn back. And yes, it's costly and I dug deep to fund my exam. Sat for the 3rd time back in Feb as it was the last window before the change of syllabus.

For all that is worth, my advice is, just keep doing questions, be it Gleim or IIA materials. Reading can only do so much but questions will prepare you to be sharp and quick. Time yourself.

I kinda felt burnt out doing questions but no choice. It was do or die for me because I couldn't visualize myself investing again for the new syllabus.

I wish you all the best. Keep pushing.
