What's the actual passing score for TANKER? Getting conflicting info

For what it's worth from someone who's been through it:

The TANKER is one of those exams where the practice tests really do prepare you well. The style of questioning is pretty consistent. If you're comfortable with "tanker familiarization course" material under timed conditions, you'll be fine.

The one thing I'd add: read the question stems very carefully. They sometimes add a qualifier that completely changes the right answer and it's easy to miss when you're going fast.

Also check whether you need to schedule the exam in advance — some testing centers book up 2-3 weeks out.

Quick update: just cleared 80% on my most recent tanker-familiarization practice set using free tanker environmental regulations and compliance familiarization. Sitting for the real thing in 4 weeks. Feeling cautiously optimistic.

For anyone finding this later: tanker-familiarization is passable with consistent effort even working full time. I studied 58 minutes a day for 13 weeks. The free tanker environmental regulations and compliance familiarization kept me honest about my actual gaps.

I'm in the same boat honestly. I've been drilling practice questions all week and just hit 82% on a mock run, which felt pretty solid. The score thing confused me too at first but from what I've found it's mostly 70% as the baseline, though some employers and state requirements stack extra criteria on top. I spent a lot of time on the cargo properties section specifically because it kept tripping me up, and doing the free tanker familiarization cargo properties and hazards questions helped me get comfortable with that material fast.

Planning to sit the real exam next Thursday. Wasn't feeling ready two weeks ago but the practice scores are consistent now so I figured I'd just go for it. Good luck with yours.

The 70% vs 75% confusion is real and I went through the same thing. From what I gathered it depends on which endorsement you're going for, because the requirements aren't all the same across the board. When I took mine the passing score was 80% actually, so I'd honestly just call your local testing center directly and get it from them rather than trusting random forum posts (including this one lol).

What helped me way more than chasing the passing score was focusing on understanding why the wrong answers are wrong. Like if you just memorize "the answer is C" you're gonna blank under pressure, but if you know why the other three options don't make sense you can work through stuff you've never seen before. For tanker fam specifically the cargo compatibility and emergency procedure questions tripped me up until I actually understood the reasoning behind the regulations, not just the rules themselves. That shift in how I studied made a pretty big difference.
