My neighbour is a lecturer. She told me some important points to keep in mind for any subject semester.
Look for the questions that you are best versed in and attempt those first. Go in descending order i.e., from best to worst. This will help maintain the quality of your answers.
Writing in points will give you bonus marks. Black pens are not allowed so don’t use them. Highlight the parts of the answer you wish to be seen by the examiner first.
Draw neat labelled diagrams of appropriate size. Note that the size of the diagram has nothing to do with your marks.
Another way to improve the quality of your answers is to use the required technical words.
Neat handwriting will definitely get you some brownie points. There should be proper spacing between two words.
The trick that will surely get you a few more marks is to highlight important parts while you are writing the answers. You may use the same pen or even pencil. In case you don’t know the answer to a question, focus on the keywords in the question and write your answer based on them itself.
