00:00Hello future doctors, researchers and bio-enthusiast, this is Aditi Khanna from Orchids International

00:17School, Jabalpur.

00:20Your CBSE 12th board examination of biology is approaching and I know you want to score

00:26big but just studying hard is not enough, you need to study smart.

00:32In this video, I'll share practical tips, common mistakes to avoid and the most important

00:39topics you must focus on.

00:42So grab your notebooks and let's get started.

00:47Biology is not just about reading, it's about understanding, retaining and presenting well

00:53in the examination.

00:56Here is how you can maximize your score.

01:00First of all, to keep in mind that your NCRT is your Bible.

01:05Almost 100% of the paper comes from your NCRT.

01:11Don't just read, few things you have to memorize, for example, some key definitions, diagrams

01:18and in text questions.

01:21In biology, a well labeled diagram can get you full marks even with minimal of the explanations.

01:29Focus on important diagram, revise smartly with mnemonics because in biology sometimes

01:38we struggle to remember examples and processes.

01:42Use mnemonics and memory tricks to memorize such things.

01:49Practice previous year papers.

01:50The next key mantra is to practice previous year's paper, solve at least five years of

01:57the previous year papers, pay attention to the repeated questions, especially from genetics

02:05and evolution.

02:08Even the best student make mistakes, but you won't because you will know exactly what to

02:15avoid.

02:17First of all, skipping labeling in the diagrams, even if your diagram is perfect, no labels,

02:25no marks, always label neatly, use pencil and underline keywords.

02:32The second thing that biology is not about essay writing competition, examiners prefer

02:40answers in points, not long paragraphs.

02:44It's quite boring.

02:45Be concise and to the point while you're writing your answer.

02:50Thirdly, forgetting to highlight the key points.

02:54You have to highlight the key points, underlining or highlighting the key points can grab the

03:00attention of the examiner while correcting your answer sheet.

03:07Next is that you have to keep focus on the marking scheme, never ignore your marking

03:13scheme.

03:15If a question is for five marks, break your answer into at least five points.

03:20If it is for two marks, don't overexplain.

03:23If it is for one word, write that one particular word that is being required over there.

03:30Now let us focus a little on the most important topics for biology.

03:36You all must have studied that unit two carries the maximum of the marks among all units.

03:43So genetics and evolution, Mendelian genetics, DNA replication and transcription, genetic

03:51disorders like sickle cell anemia, hemophilia.

03:56Then coming the next one to the biotechnology, the unit of biotechnology and its application.

04:03It includes recombinant DNA technology, PCR and DNA fingerprinting and especially the

04:10most emphasized topic must be that the application of biotechnology in the field of medicine

04:17and agriculture.

04:19Then coming to the last one, that is ecology and environment.

04:24You must focus on population growth curves, biodiversity conservation and economic interactions.

04:34If you master these topics, you are already on track for 90% marks.

04:42Now listen to me carefully.

04:45Your biology board examinations are not your enemy.

04:50It is an opportunity to showcase what you have learned.

04:55Every great doctor, scientist and researcher once sat where you are today, nervous, uncertain

05:05but determined and here is the truth, you are ready.

05:11Keep going, keep believing and on the exam day walk in with confidence.

05:16Wish you all a very good luck.
