Which test series should i take altus knowledge or allen for iit

But altus contains questions  which appears in real adv exam

Hello,Considering the test series only, there are many institutes and web sites that are offering many test series and are claiming to be the best. Claiming something and having actual facts are a two different things. Allen and Altus knowledge are almost on the same page when it comes to offering test series.Allen has a wide variety of sets and questions available online to practice, however are little bit heavy on the pocket. But when it comes to Altus knowledge, I have seen them, they have much better quality of questions, no repititions or same questions with different values and even they won't have weak and easy to crack questions.Although, they both are having a good competition with each other, there are multiple options also available. You can give it a try with either of them considering the budget you have and feasability they offer with the services.Moreover, Altus is known to claim that there questions will be almost the same question that one will see while appearing in the exam, which is something no one can match. Allen also have good questions but they haven't claim anything in the past nor today even, while Altus is stable at their promises with their customers and students.
