For TFE, I found that the CDP video answers were pretty helpful and the technique they use to imagine which sides are touching really helped me out. I would recommend to keep on doing Bootcamp, Crack DAT, and Achiever...the last one is a bit of a confidence killer but if you honestly just treat it as practice / a learning lesson, it's incredibly helpful. I found the Achiever PAT to be harder than the actual DAT so it helped me over prepare for the PAT on the actual DAT. With CDP, I would be a bit careful because the line counting method doesn't work on the real DAT.
