In January I started ready my 950 page Sybex CISSP book. Around March/April onwards I lost tons of momentum and have barely touched it since.
But ive learned tons and I have 3 chapters left and will have them finished in 2-3 weeks.
Im just wondering what to do next. I know it's a hard question as I don't know (and you don't know my knowledge level).
Wondering if i should do:
A) Read the 600 page Conrad book to further cement the knowledge and re-learn anything i missed or have forgotten

Go onto Boson questions. I get most of these wrong. But my idea was to do 10-15 and any I get wrong I will spend 10 minutes looking up the topic, doing a cue card and learning from my mistake
C) any other tactic?
...
I'm not sure I have the energy to go through another big book. So I'm leaning more towards questions+videos+podcasts.
Any thoughts on this?
