Your numbers look solid at first glance, but there's a couple of traps I see often.
1. calculator traffic is a classic zero-click problem.
People get the answer directly in Google's featured snippet or the knowledge panel. That's not a CTR issue-it's a search behaviour issue. You can check your GSC data: if those pages have high impressions but near-zero clicks, you've confirmed it.
2. Position 7.5 is bottom-of-page-one hell.
CTR won't budge until you crack the top 3-that's a ranking problem, not a title tag or meta description problem. I'd pull a report from Ahrefs to see the exact CTR curve for your industry, it usually drops off a cliff after position 3.
3. for online MBA terms, you're up against universities with thousands of referring domains.
Start with education directories and course listing sites (e.g., Course Report, MBA.com listings). They're relevant, often free, and faster to get than outreach to bloggers. Use Screaming Frog to audit your internal links and make sure those pages have enough link juice flowing in.
Give it another 3 months before re-evaluating. The foundation looks fine-you just need time and a targeted backlink strategy for that niche.
