hello aspirant,

the test series is very good for the aspirants who are willing to give their best at the JEE MAINS level. you should definitely try the test series online but if you also want to go for jee advanced , then you have to prepare from other paces as well, you have to try out other test series as well because the level of questions in this test series won't be enough to match the level of JEE ADVANCED

hope that helps
