Opinion?

I had taken Kaplans SIE workbook during my time at the firm. I took the test 2 times, first I got a 66% 2nd attempt I got a 69%. Missed it by 1%. Was depressed for a bit didn’t think this was the right industry for me because of these tests. I took a year off, now I’m back. I have 1 more chance to take the SIE to motivate to move forward in the business. I have bought STC, any thoughts ?

Also, any other study advice would be much appreciated. My memorization isn’t the best, so I do need to know the material.

Thanks in advance !
