Which mock test are best for JEE advanced?

My two cents here: There are a lot of JEE mock tests doing the rounds on the internet. Coaching institutes are after students to pick their mock test series. A lot of answers here seem to be from those institutes only. Allen mock tests are decent but for JEE advanced mock test, they have mixed reviews. FIIT JEE used to be good but haven’t found their mock test series up to the mark especially JEE advanced mock test series. Resonance I haven’t tried yet. Aakash does have multiple online and offline options of JEE advanced mock tests with analysis, all India ranking etc. Kaysons has lots of suggestions on Quora but I don’t trust those to be genuine. Before choosing a JEE mock test series remember these things to consider when choosing a JEE mock test series:

1. How extensive is the mock test series is? Based on the difficulty level choose the one that mirrors the actual JEE advanced exam.
2. Performance analysis – some institutes do provide post-test question paper and performance analysis for each student individually. Look for the one that offers all India ranking as it gives you a real idea of competition at a much broader level
3. Support from faculty or subject experts – Look for JEE advanced mock test series that gives you an option of discussion sessions with faculty or subject experts. Some institutes arrange for online video sessions for students appearing for mock tests.
4. Online Availability – This one is a critical feature. Choose JEE advanced mock test which is available online. Online tests are convenient and better as JEE advanced is conducted completely online. Also, online tests provide reports and metrics in lesser time. Don’t forget to take as many mock tests as possible to strengthen your preparation and constantly monitor your progress. JEE mock tests not only help you track your progress but also build the temperament required for the real exam. Difficulty levels in JEE mock tests help you develop the attitude required to handle the actual JEE. Once you finalise on the JEE mock test series, prepare well and give it your best. Hope you succeed in cracking JEE and secure a seat admission IIT. All The Best.
