CPhT exam — struggling with pharmaceutical calculations, any tips?

Don't neglect the sterile compounding questions — those have gotten more prominent on the PTCE in the last couple years and some people are caught off guard by how technical they get.

73% overall with 3 weeks left is a solid position. Do 20 calculation problems every single day and you'll see the scores move. The repetition genuinely works on this type of content.

Days supply tripped me up too. The key is being precise about what dispense-as-written means for different dosage forms. Inhalers and eye drops have specific counting rules that aren't intuitive if you haven't drilled them explicitly.

Your coworker is right. Dimensional analysis is the way — once you get the method down you don't need separate formulas for every calculation type. It takes about a week of focused practice to click but then it's reliable under pressure.

Honestly the thing that finally moved my math scores was changing how I reviewed. I stopped just checking which answer was right and started forcing myself to figure out why each wrong one was wrong. For IV flow rates especially, the distractors are usually one unit conversion off or they flipped mL/hr and gtt/min, and once you see that pattern you start catching your own mistakes before you make them. Days supply was the same deal for me. I'd get it wrong, then go back and trace exactly where the dose-per-day setup broke, and it stuck way better than memorizing a formula.

It's not really subject specific either, it's just a study habit. I do the same thing on totally different question banks when I want the reps, like this one for cma/questions/fetal monitoring assessment, where I'll deliberately read every wrong choice and ask what would have to be true for that to be correct. Sounds slow but it cut my careless errors a ton. Give it two weeks and I bet that 61 climbs.

Just wanted to pop in with a quick update since I posted last week freaking out about the same stuff. I took a full practice test yesterday and hit 79%, which honestly felt like a miracle after how rough things were going. The calculations section is still my weak spot but I'm getting better at slowing down and writing out the units before I do anything else.

I've got my exam scheduled for the 24th so I'm in crunch mode now. If you're struggling with IV flow rates specifically, just drill the formula over and over until it's automatic. It's not about understanding it deeply, it's about not second-guessing yourself mid-problem. You've got this.

I just passed my CPhT last month and honestly the thing that saved me on calculations was stopping trying to memorize formulas and just picking one method for each problem type and drilling it until it was automatic. For IV flow rates I always set it up as a fraction chain, every single time, even when it felt like overkill. Once I stopped switching between methods depending on how the question was worded, my accuracy shot up fast.

The other thing that actually helped was doing a few problems right before bed instead of grinding a 2-hour session. Something about it just clicked better in smaller chunks. At 61% you're not far off, you probably understand the concepts more than you think and it's just the setup that's tripping you up. Write out your units every step and don't skip anything even when it feels obvious.
