Exponent now operates as Aced (its pricing page reads "Aced (formerly Exponent)"). It is a broad membership with courses, video answers, peer mock interviews and an AI Engineering track. If you mainly need AI engineer prep (RAG, agents, LLM system design, evaluation), the alternatives below range from a free question bank to one-time guides and other subscriptions. Prices were read from each seller's own page on Nov 2, 2026.
What Aced (formerly Exponent) offers
- Plans: Basic is free (sample lessons, 5 peer mocks per month, sample questions, basic job referrals). Pro lists $79 per month, or $12 per month on the annual plan. Expert lists $99 per month, or $20 per month on the annual plan, and adds the AI coaching suite. Source: >aced.io/upgrade.
- What Pro includes: all courses, video and written solutions, company-specific guides, unlimited peer mocks, the full question database, priority job referrals and a Discord community.

Aced does a lot well: peer mock interviews, video answers and coverage of many roles beyond AI engineering. Choose an alternative if you want a one-time purchase, a narrower AI-only focus or a free starting point.

How to choose
- You need live practice with people: stay with Aced, whose peer mocks are its strongest feature. No PDF replaces a person asking follow-ups.
- Your loop is mostly system design: compare Aced with Hello Interview, which centers on system design and AI mock interviews.
- Your loop is LLM-heavy and your budget is small: start with the free AI engineer question bank, the timed mock round and the answer self-check, then add a one-time guide for the gaps.
- You prefer to own the material: a book or PDF is a single payment with no renewal to cancel.
Cost over a typical prep window
Prep windows vary, so compare the total you would actually pay, not the headline monthly number.
| Prep window | Aced Pro monthly | Aced Pro annual | One-time guide ($19.99) | Free bank |
|---|---|---|---|---|
| 1 month | $79 | 12 x $12 = $144 billed for the year | $19.99 | $0 |
| 3 months | 3 x $79 = $237 | $144 billed for the year | $19.99 | $0 |
Annual totals assume the annual plan is billed as 12 months at the listed monthly rate; check the checkout page for the exact charge.
