CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

My exam was terminated because I checked the time on my phone during the break. I was wondering if I get to take the exam again, and if so do I need to pay the full price? I took the exam through ets.org if it matters. Source: about 1 year ago
I don't think you can go wrong, though. I think you should take a practice exam for the GMAT (from mba.com) and then take a practice GRE (from ets.org) and compare the results. That should help give you the clarity you're looking for. Source: about 1 year ago
I just took both of my baseline tests this week (ets.org for GRE and MBA.com's first free test for GMAT). Source: over 1 year ago

For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: about 2 years ago
