Thanks guys for your feedback. My hard luck is that I started off by preparing for the lateral exams as it is a weak strength for me (living and working on the east coast) and was planning to catch up on the vertical while nearing the exam; however I guess we have till Feb 24 to apply for any refund; so will have to call the shot before that. I just hate the drudge to go back in study hibernation for another 6 months and pass the remaining exam.
"Nothing ventured, nothing gained" - I think that either way is going to be OK, the main thing is it's better to try than not at all - so fair play to you! There's pro's and con's of either approach, but for me the biggest thing is time management. If you are taking both components together, you need to make sure you invest the time.
I took both components for the first time in April 2021 (Depth Bridges), started studying 2nd week of January with AEI-California courses, and passed Vertical and failed Lateral (23/40 and A/A/A) and passed Lateral in October. For me it was worth it to take both at the same time, as I only needed to pass 1 and I could focus entirely on the other component the next cycle. Personally I would recommend you focusing your time on primarily preparing for the Vertical (largest scope but easier based on your experience) and have Lateral be your secondary focus.
Here's my suggestions, hopefully you might find them useful:
* Plan out your available study time and stick to it. Don't push off reviewing your strongest topics until the end (like in my case - I didn't study AASHTO depth until the very end for both Vertical and Lateral because I was too focused on studying what I didn't know - i.e. buildings).
* Organize your notes into subject-specific binders and add tabs for quick reference. Develop a key for examples that you can find quickly during the exam.
* Put together a quick reference binder (i.e. "cheat sheets"). In there I put only a few sheets from each subject that I used to solve most AM questions without opening my more detailed subject-specific binders. For instance, for Bridges-Lateral I had the AASHTO Load Combinations, all AASHTO sheets related to seismic analysis/design (there aren't that many - and you can mark them up), equations for pier stiffness, examples on SM/UM analysis, etc...
* Do as many example problems as possible
* Learn exam strategies. For instance in the AM, read through the first 10 questions slowly without answering any of them. Mark the difficulty of each as 1(easy), 2(moderate), 3(difficult). Then go back and answer all of the 1's and 2's, skip the 3's. Repeat for the next 10 questions, etc... You don't want to get to the end of the exam with 5 easy questions left but only 5 minutes left to solve - best to solve the low-hanging fruit first.
Hope this help...
