Scholaranium Release – Nov 2018 – Improving percentile to ability mapping

A 3 min read

Release type:  Minor

Release Brief:

At e-GMAT, we always look to improve. Hence, we constantly update our questions, solutions and the ability estimate we provide. In this release, we have evaluated data from more than 50,000 ability quizzes, compared the same with numerous ESRs and have improved the precision of ability estimates.

Scholaranium – GMAT Club’s most loved quizzing platform

Scholaranium has played a huge role in student’s success since its launch in 2015. Since then, thirty thousand students have answered more than 9M questions, and taken more than 200,000+ ability quizzes and 350,000+ custom quizzes. The platform’s daily traffic has grown from 2000 question attempts per day in 2015 to more than 15,000 question attempts per day today. It’s no surprise that Scholaranium is the highest rated (4.8) quizzing platform on GMAT Club, rated higher than GMAT Prep mock tests (rated 4.0) and Manhattan GMAT CATs (rated 4.3).

How has Scholaranium helped students?

There are three ways in which Scholaranium helps students.

  1. It provides students with more than 2,000 high-quality questions with detailed solutions.  These questions, as well as solutions, are updated regularly to reflect the latest GMAT trends.
  2. The second feature that students love the most is ability quizzes. Scholaranium allows students to take 60+ ability quizzes that inform students of their level of preparation. This means that a student aiming for V40 can take a Sentence Correction ability quiz after studying for Sentence Correction and ascertain whether he/she has reached the required level of proficiency. In case the student does not reach the required level of proficiency, the accompanying analytics point out the areas that likely need to be worked on.
  3. Lastly, the custom quizzing feature in Scholaranium allows students to confirm that they have really improved after studying for as few as 4 hours.

Below are a few quotes from students!!

“Scholaranium indicated that Boldface was a problem area. I went back to the Concept files to understand the errors and then confirmed my improvement in Scholaranium” – Link to debrief.

 

“The course helps you understand the topics and Scholaranium is a beautiful portal where you can practice and excel the topics you’ve learned.” – Sumanth(Q51) – Link to review

 

“Taking customized quizzes time to time helped me retain the strategies learned from the modules. Also, I simulated full gmat verbal section experience selecting 36 questions spreading them across topics and difficulty levels. Scholaranium questions are more than sufficient and gave me ample practice.”  – Link to success story

Release Nov 2018 – Make ability estimates more precise

At e-GMAT, we always look to improve. Till now, anyone who used to take any ability quiz was provided a percentage score, which was a weighted average of all the questions, of varying difficulty, which the student got correct in the test. After seeing this score, the student might wonder, is 70% good or bad or decent?

So, to help the student understand his performance better, we have decided to show the student his percentile instead of the percentage score!

Now, your ability score is percentile ranking or how you rank amongst the spectrum of GMAT test takers. For example, students who get a weighted average score of 70 on Sentence Correction ability quiz will now see their ability score to be 84 percentile, indicating that they have managed to perform better than 84 percent of the students who take the test. Similarly, combining the ability scores from Critical Reasoning and Reading Comprehension, the student can estimate their Verbal ability scores (or verbal score out of 60).

While this may seem like a small change, this change will give students insights about their performance and will help them plan their preparation better.

Click here to take an ability quiz in case you want to give Scholaranium a spin. Otherwise, write to acethegmat@e-gmat.com if you need help preparing a customized study plan.
