Currently, have been using achievable as a huge supplement from firm provided materials (STC), genuinely prefer the textbook on achievable.
Scores:
KM Benchmark - 80
STC - 83,74,91 (most recent)
Achievable - 78
The plan is trying to re-read the textbook at least once more, and maybe take notes and supplement with more practice exams and YT videos.
The textbook is just amazing, simplifies the content in simple English, but am afraid I might be on the ambitious side to reread it all while working FT, but am going to try. Open to advice on filling in the gaps, and just executing. Thanks for everything, passed the SIE by supplementing info last month and achievable was a huge part of that.
