Short answer
Your preparation decides the result, and no chart can promise a pass. If the exam date is fixed, sit it and put your energy into revision, practice papers and sleep. If you can choose between sittings, tradition favours a day outside your Chandrashtama (when the Moon is 8th from your Moon sign) and a start time outside Rahu Kalam where possible.
How ChiChakra reads this
Astrologers link learning to the 4th house (education), the 5th (intelligence and exams), Mercury (study and memory) and Jupiter (wisdom), alongside the running Dasha. For day-to-day timing we check the Moon: Chandrashtama comes once a month and lasts about 2 to 2.5 days.
Getting exam-ready
Do timed past papers and list the topics where you keep losing marks. Spend most of your remaining time there.
Sort the admin early: registration, ID, the venue and any access arrangements.
Mercury is retrograde until 13 November 2026 and again from about 11 February to 5 March 2027. Traditionally that suits revision and re-checking, so use it to go back over weak topics.
Never miss an available sitting or deadline for an astrological preference.
Good to know
If exam stress is affecting your sleep or mood, talk to a teacher, a family member or someone you trust.
