I was able to pass on my first attempt as well. I went to school in NY and worked retail but I haven't actually practiced in a couple of years. I used an outdated handout from Texas Tech from 2013, a CVS handout from 2014, a question bank that was from Sarah Fichuk's "Pass the Texas Pharmacy Law Exam" from 2016, read the DEA Pharmacist's manual, cross-referenced stuff with the TSBP Master Rule book, read the CE law and sterile compounding handouts on the TSBP website, and the 2019 supplement to "The Ultimate Texas MPJE Review Guide". Wouldn't exactly recommend studying the way I did but life's mistakes kinda forced me into this. Studied for 10 days-ish. Got my exam results after 3 days. Came out of the exam thinking I bombed it but ended up doing okay. For the ambiguous questions, I asked myself "What would I do in practice?". My general answer is "cover my ass and then do what's I can for the patient". Guess that mindset worked because I passed. Best of luck to you guys - on this test, and in life.
