Short answer
The best consulting assessment prep platform is the one that simulates the test you will actually take. We compared six platforms on BCG Casey, Bain SOVA and McKinsey Solve coverage, content depth, pricing and update frequency. DrillCase is our product and is included, so we disclose our method and note where competitors fit better.
Key takeaways
- Assessment-specific simulation matters more than general case interview content for the online test stage.
- Coverage differs widely: some platforms simulate one firm's test, others offer only guides or peer practice.
- This comparison is written by DrillCase; the method section explains how we tried to keep it fair.

Part ofConsulting Online Assessments: Which Test Will McKinsey, BCG or Bain Send You?
Consulting assessment prep platforms are online tools that help candidates practice for the digital assessments used by McKinsey, BCG, Bain, and other consulting firms. The best platforms offer realistic simulations that match the actual test format, not generic case interview practice.
The consulting recruiting pipeline has fundamentally changed. Before you ever sit down for a live case interview, you must pass an online assessment — BCG's Casey chatbot, Bain's SOVA aptitude test, or McKinsey's Solve simulation. Many candidates are eliminated at this stage. The platform you choose for assessment prep directly impacts whether you advance or wait 12 months to reapply.
We evaluated six major consulting assessment prep platforms across format coverage, content depth, pricing, and update frequency. This comparison reflects research conducted by the DrillCase team using publicly available product information, candidate debriefs, and direct product testing where possible. We include DrillCase in this comparison because we built it to address gaps we identified in the market — and we believe an honest side-by-side comparison serves candidates better than marketing claims alone.
Why You Need Assessment-Specific Prep (Not General Case Prep)
Traditional case interview preparation — frameworks, profitability trees, market entry analysis — prepares you for a conversation with a human interviewer. That is valuable, but it does not prepare you for the digital assessments that come first in the recruiting pipeline.
The BCG Casey chatbot is a timed digital interface with data exhibits and no back-and-forth dialogue. The Bain SOVA is a psychometric aptitude test with verbal, numerical, deductive, and inductive reasoning sections. McKinsey Solve is a gamified simulation testing pattern recognition and systems thinking. None of these formats resemble a traditional case interview.
Candidates who prepare only with general case materials consistently report being surprised by the actual assessment format. In candidate reports, the most common reason given for assessment failure is not lack of business knowledge — it is format unfamiliarity. You need a platform that simulates the specific assessment you will face, not one that teaches generic consulting skills.

Platform-by-Platform Breakdown
DrillCase
DrillCase covers all three major MBB assessment formats in a single ecosystem: 25+ BCG Casey-style chatbot cases, 450+ Bain-style aptitude questions, and 20+ McKinsey Solve-style scenarios. Content is modelled on candidate reports and revised when formats change.
DrillCase's core differentiation is format fidelity. The platform enforces real time constraints, replicates the chatbot interface, and includes data exhibits modeled on actual assessment content. Entry points start at $20 for a single SOVA module, rising to the $250 All-Access Pass — one payment that unlocks every DrillCase firm product for life, including everything we ship later.
DrillCase also offers three free drills (free account required): Mental Math Drills, Market Sizing Practice, and Chart Interpretation — plus a 63-case library of full case studies, free with an account.
CaseCoach ($299-599)
CaseCoach offers human coaching sessions and structured case prep curriculum, primarily targeting MBA students at top programs. The platform is strong for live case interview preparation — experienced coaches provide personalized feedback that AI tools cannot fully replicate.
However, CaseCoach does not simulate digital assessment formats. There is no BCG Casey chatbot simulation, no Bain SOVA question bank, and no McKinsey Solve practice. CaseCoach prepares you for the interview stage that comes after the online assessment — if you pass the online assessment first. At $299-599 for coaching packages, the price point also excludes many budget-conscious candidates. CaseCoach and DrillCase solve different problems and are complementary rather than competitive.
PrepLounge ($29-99/mo)
PrepLounge is a peer-to-peer case practice matching platform with a large community of consulting candidates. The platform connects you with practice partners for live case discussions — valuable for building interview skills and getting immediate feedback from peers.
PrepLounge does not offer digital assessment simulations for any MBB format. There is no Casey chatbot practice, no SOVA question bank, and no McKinsey Solve simulation. The quality of peer practice also varies significantly — you may be matched with beginners who cannot provide meaningful feedback. PrepLounge is best used alongside an assessment-specific platform like DrillCase, not as a replacement for it.
MConsultingPrep (~$250)
MConsultingPrep offers a Casey chatbot simulation and consulting prep courses. The platform has been available for multiple recruiting cycles and has an established brand in the consulting prep market, particularly in Asia.
MConsultingPrep's Casey simulation is priced at approximately $250 — higher than DrillCase Complete ($199 for 20 Casey-style cases). The platform does not offer Bain SOVA preparation or an interactive McKinsey Solve simulation, limiting its utility for candidates targeting multiple MBB firms. Debrief sourcing methodology and update schedule are not publicly documented.
CaseBasix ($70)
CaseBasix offers 10 BCG Casey chatbot practice cases at an accessible price point. For candidates who are only targeting BCG and want a focused, affordable option, CaseBasix is a reasonable choice.
The limitation is scope: only 10 cases (versus DrillCase's 25+), no Bain SOVA preparation, no McKinsey Solve simulation, and no publicly committed update schedule. For Casey-only prep on a tight budget, CaseBasix works. For comprehensive MBB assessment coverage, DrillCase provides significantly more value.
JobTestPrep ($39-89)
JobTestPrep is a broad aptitude test practice platform covering SHL, Kenexa, Cubiks, and similar assessment formats across many industries. The platform offers generic verbal, numerical, and logical reasoning practice at affordable prices.
JobTestPrep's content is not calibrated specifically to Bain SOVA difficulty or format. The questions may be too easy, too hard, or structured differently from what you will encounter on the actual SOVA assessment. For general aptitude test practice, JobTestPrep is solid. For Bain-specific SOVA preparation with questions written to the format candidates report, DrillCase provides a more targeted solution.
Which Platform Is Right for You?
The best platform depends on your target firm, budget, and preparation timeline. Here is our recommendation by persona:

How We Evaluated These Platforms
This comparison was produced by the DrillCase team. We acknowledge the inherent conflict of interest in evaluating platforms that compete with our own product. To maintain credibility, we applied the following methodology:
- Format coverage: We documented which assessment formats each platform supports based on their publicly available product pages and feature lists. We did not speculate about features that are not publicly documented.
- Pricing: All prices were sourced from public pricing pages as of June 2026. Prices may change. Where pricing was not publicly listed, we noted the approximate range from third-party sources.
- Content sourcing: We noted whether each platform publicly documents its content sourcing methodology (candidate debriefs, coach expertise, community contributions, etc.). Where sourcing is not documented, we said so rather than assuming.
- Update frequency: We noted publicly committed update schedules. Where no public commitment exists, we said "not committed" rather than "never updated."
- Competitor descriptions: We described competitor strengths honestly. CaseCoach provides excellent human coaching. PrepLounge has a large, valuable community. JobTestPrep covers a broad range of aptitude tests. Each platform has genuine merits.
If you identify any inaccuracies in this comparison, we welcome corrections. Our goal is to help candidates make informed decisions, not to misrepresent competitors.
Frequently asked questions
What is the best platform to prepare for BCG Casey?
DrillCase offers 25+ BCG Casey-style chatbot cases with 250+ questions, each case timed with exhibits in the chatbot format candidates report. CaseBasix offers 10 Casey cases at $70, and MConsultingPrep offers a Casey simulation at about $250. DrillCase plans start at $99 for 14 cases, with 20 cases at $199 and every case at $350.
Do I need a different platform for each consulting firm?
Not necessarily. DrillCase covers all three major MBB assessment formats in one ecosystem: BCG Casey chatbot simulation, Bain SOVA aptitude questions, and McKinsey Solve simulations. If you are applying to multiple firms, using a single comprehensive platform saves time and money compared to juggling separate tools. However, if you are targeting only one firm, a single-format tool may be sufficient.
Is it worth paying for consulting assessment prep?
Yes, for most candidates. Consulting firm online assessments screen out many applicants, and the format is unfamiliar to most candidates. Paid platforms offer format-specific practice that free resources cannot match — timed simulations, realistic interfaces, and calibrated difficulty levels. DrillCase offers entry points from $20 for a single SOVA module, making paid prep accessible even on a student budget. The cost of preparation is minimal compared to the career impact of passing or failing a one-shot assessment.
How far in advance should I start preparing for consulting assessments?
We recommend starting 3-4 weeks before your expected assessment date. Week 1 should focus on understanding the format and identifying weaknesses through diagnostic practice. Weeks 2-3 should involve targeted practice on your weakest areas with timed conditions. Week 4 should be full-length simulation practice under real test conditions. If you have less time, prioritize format familiarity — even a few days of format-specific practice significantly outperforms going in cold.
Can free resources replace paid consulting assessment prep platforms?
Free resources are excellent for foundational skills — DrillCase itself offers free Mental Math Drills, Market Sizing Practice, and Chart Interpretation with a free account, plus a 63-case library of full case studies with exhibits and model answers, free with an account. However, free resources cannot replicate the timed simulation experience of the actual assessment interface. For BCG Casey and Bain SOVA specifically, format-specific practice under real time constraints is what separates candidates who advance from those who do not. Start with free tools, then invest in format-specific simulations as your assessment date approaches.
