We have a simple to use and understand grade chart so that you can calculate correct grades at once.
Step 1️⃣ See the number running at the top of the chart. They are the total number of questions in the exercise.
Step 2️⃣ Now look at the number of correct answers in the column located on the left of the chart.
Step 3️⃣ Find the point where these two lines meet. This will show you the percentage of your correct answers.
For Example: If there are 25 answers but you have got 22 answers right. Find 25 at the top of the percentage chart. Then find 22 at the left side. Now locate the place where these two lines meet which is at 88. This would be your correct percentage.
