The official ICAI announcement states that the mock tests are available in physical and virtual modes. Students using the online route can download question papers through the BoS Knowledge Portal or BoS MTP Registration Portal and attempt them within the prescribed paper duration.

How to access the mock papers

ICAI says question papers for each subject are uploaded on the BoS Knowledge Portal or the BoS MTP Registration Portal by 9:30 AM as per the schedule. Students should download the paper and attempt it within the stipulated time limit rather than using it only as an untimed practice sheet.

For physical mock tests, students may approach the relevant ICAI branch or regional office. ICAI's registration instructions for the MTP portal require student login, registration number and date of birth for first-time registration, followed by the registered email ID and OTP for login.

When are answer keys released?

ICAI states that answer keys are uploaded within 48 hours from the date and time of commencement of the respective paper. Students can then compare their attempt with the answer key and assess performance.

How to use the mock tests effectively

- Attempt in exam conditions: follow the official duration and avoid pausing the paper.

- Review within 48 hours: compare your attempt with the ICAI answer key while the mistakes are still fresh.

- Classify errors: separate concept gaps, calculation errors, poor question selection and time-management problems.

- Use Series II as a second benchmark: revise weak areas identified in Series I before the second series begins on 20 August.

- Do not rely only on mock scores: use the papers as a diagnostic tool alongside the applicable ICAI study material and examination preparation.

Key takeaway

For CA Foundation September 2026 candidates, the immediate ICAI mock-test dates are 14 August for Quantitative Aptitude and 17 August for Business Economics, followed by Series II from 20 to 27 August. Students should use the official timed format, download papers through ICAI's BoS platforms and review the answer key within the stated 48-hour publication window.
