Problem solving training for computer science students.
This level simply consists of eight sheets, three of them on Codeforces OJ, plus four of them on HackerEarth OJ, and the last one on HackerRank OJ.
The prerequisites for level 1 of this training are the basic knowledge for any programming language like (Variable Types - Basic Operators - Conditions - Loops - Functions - Lists - Strings).
Codeforces OJ sheets
Codeforces OJ sheets
The Codeforces OJ sheets codeforces - phase 1-1, codeforces - phase 1-2, codeforces - phase 1-3 contain A-Div2 problems, and each sheet of them divided into 5 classes of problems (Basic Operators - Conditions - Loops - Lists - Strings). These sheets were sorted based on difficulty and grouped by the type of problems as mentioned. Finally, each sheet contains ~100 problems.

HackerEarth OJ sheets
HackerEarth OJ sheets
The HackerEarth OJ sheets hackerearth - phase 1-1, hackerearth - phase 1-2, hackerearth - phase 1-3 contain implementation problems and basic programming problems. These sheets were sorted based on difficulty. Each sheet contains ~100 problems. For the last sheet hackerearth - phase 1-basic-programming that focus on the basic programming problems, It's divided into 4 classes of problems (Input/Output - Bit Manipulation - Recursion - Operators). Also, this sheet was sorted based on difficulty and grouped by the type of problems as mentioned. Finally, this sheet contains ~130 problems.

HackerRank OJ sheets
The HackerRank OJ sheet hackerrank - phase 1-functional-programming, It's divided into 6 classes of problems (Introduction - Recursion - Functional Structures - Memoization - Ad-Hoc - Misc). Also, this sheet was sorted based on difficulty and grouped by the type of problems as mentioned. Finally, this sheet contains ~80 problems.

- If the student has a target to compete in the programming competitions like ACM-ICPC or Google Codejam or Google Kick-start or Facebook Hackercup, so it's recommended to start with Codeforces sheets, but if (s)he has a target to practice on a specific topic or preparing for an interview, so it's recommended to start with HackerEarth and HackerRank sheets.
- On each one of these sheets has an excel sheet to record your effort and enhance your progress, The time estimate for level problems is between 30 min to 45 min for each one, including reading time, thinking time, coding time, debugging time, and learning time.
This level simply consists of eight sheets, four of them on Codeforces OJ, plus two of them on HackerEarth OJ, and the last two on HackerRank OJ.
The prerequisites for level 2 of this training are the basic knowledge for Data Structures and Algorithms like (Linear Data Structures - Non-Linear Data Structures - Basics Algorithms - Mathematical Algorithms).
