How to prepare for semester 4
Start with the subjects that carry the most credits, because they count most in your SGPA. For each theory subject, go through the units in order, make one page of short notes per unit and practise the long-answer questions from previous papers. Lab courses are scored on records and viva, so keep your practical file up to date every week instead of writing it at the end.
