In case you have less time focus on prioritizing key concepts while studying. Focus on previous year question papers, manage your time effectively, and reach out to teachers for guidance. It's ideal to start early, even a focused last-minute effort can help you perform well, though you might need to accept that your results may not be as high as with extensive preparation. 
Following are some strategies to consider if you're short on time for JKBOSE 12th board exams:
Figure out important topics: Analyze the syllabus and prioritize the most important chapters.

Practice past year question papers: Utilize previous year question papers to understand the exam pattern and practice answering questions under time pressure.

Make a focused study plan: Allocate specific time slots for each subject as per their weightage and your current understanding, focusing on quick revision and targeted practice.

Ask help from teachers: Consult your teachers for guidance on important topics, doubts clarification, and potential study strategies.

Focus on understanding, not just memorizing: Try to grasp the core concepts rather than simply cramming information.

Time management: While solving practice papers, ensure you can answer all questions within the given time.

Stay calm and positive: Avoid stressing out and maintain a positive attitude to maximize your focus during study sessions.

Eat Healthy and Exercise: Avoid junk food and eating from outside. Drink lot of water. Take short breaks so that you can relax.

Stay away from social media as much as possible: This will rob you of the important time that you can utilise to study and score well

Amines are organic compounds derived from ammonia (NH3 ) by replacing hydrogen atoms with alkyl or aryl groups. They are classified as primary, secondary, or tertiary based on the number of hydrogen substitutions. Their nomenclature follows IUPAC rules, using the suffix “-amine.” There are several important topics discussed throghout the chapter 9 amines such as Preparation methods, physical properties, chemical properties and named reactions.

Amines are synthesized through methods like reduction of nitro compounds, ammonolysis, Gabriel phthalimide synthesis, and Hoffmann bromamide degradation.  In terms of physical properties, Amines exhibit hydrogen bonding, affecting their boiling points and solubility. Chemically, amines are basic in nature and undergo alkylation, acylation, and electrophilic substitution in aromatic amines. Amines are widely used in chemical industries; pharmaceuticals, dyes, and organic synthesis e.g. diazonium salts, formed from aromatic amines, are crucial in dye synthesis.
