- Prepare for the Aptitude and Drawing exams by increasing your observation skills and practicing drawing.
- To for 3D/2D topic questions and other technical questions Engineering Drawing notes will be helpful.
- Break down the syllabus month wise and then weekly. Set reasonable goals but be sure to meet them.
- As individual topic mark distribution hasn't been given, spend enough time on each topic to understand the concept and be able to answer questions then move on to the next topic.
- Don't study from too many reference books as it's likely to get confusing, it's best to focus on NCERT for concepts and use previous year question banks and sample papers.
- If there are any doubts its essential to clear them as soon as possible.
- Try to study a few topics from each subject each day, for example 2 topics each from Maths, Physics and Chemistry. This helps your mind prepare for answering questions from all three subjects.
- Create separate quick revision notes for each subject. Your quick revision notes should contain important formulae, important concepts and points you feel you are likely to forget. Go through the quick revision notes as often as possible.
- For remembering definitions try studying from flash cards.
- To remember detailed notes try using mnemonics.
- Practice previous year papers/ sample papers to be able to identify trends and to find out your weaknesses.
- Keep the last 2 months for revision.
- Focus on studying topics that are your weak points and continue practicing sample papers/previous year papers.
- In the last month practice the exam papers during the same timings as the official exam, this will help you get into the habit of remembering and writing answers at that time.
- If group studies suit you try discussing physics concepts, quiz each other on chemistry topics and attempt Maths quizzes together.
- Keep reading your quick revision notes.
