You need to decide what you are struggling with in CP. It's such a vast content area. It includes OChem I/II, Gen Chem I/II, Physics I/II, and some elements of biochemistry. That's 24 credit hours of classes (more than any other section of the MCAT requires). This is why this is such a hard section to improve without putting in so much work. CP is also a section that hasn't changed THAT much - so if you're struggling with Nailing down concepts - use the older material you have. Just be cognizant of questions that test concepts that are no longer tested.
You suggested many passages which are all great for practice and hammering down concepts. But, I would start with MC questions (EK 1001 passages (super cheap book), KA free passages , Question of the Day banks, MC Qbanks from different companies) are always really good. You can really start to refine your content weaknesses this way and figure out what areas you need to work on very easily. You will find that there are some types of questions you aren't able to answer more than others. This will allow you to go revisit your content books for those topic areas (and watch KA when you really aren't getting it). This will be much higher yield than practicing passages (especially since you've made it through the TBR books). The AAMC Question Packs are also really good for identifying your weak areas (although are NOT in the style of the new MCAT)
For additional passages - the TPR Science Workbook you are referring to and own will be great after you get through many MC questions and filled in your content gaps. Many highly recommend this book along with the TBR books you have already used. CP is very conceptual sometimes, and the content review itself is also very important (along with being able to answer MC/passage questions).
If you're struggling with experimental design want passages that emulate the new MCAT - the EK 30 minute passages and the Khan C/P passages will also be good. Just remember that both of these are harder than the real MCAT by a few notches - so don't feel discouraged and just LEARN from your mistakes. Make sure to also do the AAMC section bank (although this doesn't cover all the topic areas sadly) - but still gets you good at interpreting some tables/graphs - skills you need for the new exam.
You will also make significant gains using the FLs you currently have access too. Make sure you REVIEW your incorrect answers and the content surrounding it ALWAYS. Document your wrong answers if required for both FLs and other questions you do. Review this wrong answer document when possible so you get an understanding of what types of questions you miss.
Don't get discouraged by CP and put in the work if you want to move past where you are at. The amount of content in CP can be demonstrated by:
- Khan spends 67 hours of their 144 hour MCAT playlist on this section.
- The Berkeley Review spends 6/10 books on this section
- Kaplan spends 3/7 of their books on CP
- EK spends 2/6 of their books on CP
- TPR spends 3/7 of their books on CP
- I am not as familiar with the NS set.
You should realize that it's a non-proportional amount of work to improve the CP section when it comes to content review.Put in the work and you will see results!
Also: Understand/visualize what is going on. Appreciate units. Get good at dimensional analysis, table/figure interpretation. That is half the CP section.
Also - don't ignore reviewing Ochem (not sure if you are).
