The mechanic certificate takes three knowledge tests. Here is the pass mark for each, and the retest rules, from the FAA's testing matrix and Part 65.
General: 42 of 60. Airframe: 70 of 100. Powerplant: 70 of 100. Each one passes at 70%.
Each test gets 2 hours. You need all of the tests for your certificate and ratings passed within 24 months (14 CFR 65.71). After the knowledge tests come the oral and practical tests.

Wait 30 days, or skip the wait with a signed statement from someone who holds the certificate and rating you're after, saying they gave you more instruction in each subject you failed and consider you ready (14 CFR 65.19). Either way, bring the failed AKTR to the test center.
To get the certificate you must pass all of the prescribed tests within 24 months (14 CFR 65.71). Adding a rating later has its own 24-calendar-month window for that rating's tests.
70% on each one: 42 of 60 on General, 70 of 100 on Airframe and 70 of 100 on Powerplant.
30 days, unless you bring a signed statement from someone holding the certificate and rating you want, saying they gave you more instruction in each failed subject and consider you ready (14 CFR 65.19).
24 months for all of the prescribed tests (14 CFR 65.71).
