Ques: What is biodiversity, and why is it important?
Ans: Biodiversity refers to the variety of life forms on Earth, including different species, ecosystems, and genetic diversity. It is essential for maintaining the stability of ecosystems and for humans, for providing resources, for ecological services, and for genetic material for adaptation.
Ques: What are the main features of Kingdom Fungi?
Ans: Kingdom Fungi consists of eukaryotic, nonphotosynthetic organisms bearing a chitin cell wall. They are mainly decomposers and sporebearing, with spore production both sexually and asexually.
Ques: What is an alternation of generations?
Ans: Alternation of generations is the type of lifecycle in plants where there is a regular alternation between a haploid gametophyte stage and a diploid sporophyte stage.
Ques: What characterises chordates as opposed to nonchordates?
Ans: Chordates have a notochord, dorsal nerve cord, and pharyngeal slits at some stage of their life, whereas non-chordates do not have all of these features.
Ques: What are the functions of ribosomes?
Ans: Ribosomes are involved in the synthesis of proteins within cells. They translate mRNA into particular polypeptide chains.
Ques: What are enzymes? How do they work?
Ans: Enzymes are biological catalysts that catalyze reactions with minimum activation energy; thus, metabolic processes run rapidly.
Ques: What is the role of chlorophyll in photosynthesis?
Ans: Chlorophyll absorbs light energy, mainly solar energy, and changes it into chemical energy during photosynthesis for the production of glucose.
Ques: What is the role of haemoglobin in blood?
Ans: Hemoglobin is a red blood cell protein that captures oxygen in the lungs to carry it to tissues throughout the body.
Ques: What is a synapse?
Ans: It is a junction between two neurons where nerve impulses pass from one neuron to another by chemical or electrical signal.
Ques: What does insulin do in the human body?
Ans: Insulin keeps the blood glucose concentration stable by promoting glucose to enter the cell and be stored in the liver in the form of glycogen.

Question order: Follow the right question order in the exam to prevent confusion at the last minute.
Diagrams: Include labelled diagrams wherever you can and label them on the left side if possible to keep a neat and systematic look.
Highlight key points: All the key points have to be highlighted to draw the attention of the scrutinizer.
Review your work: Before submitting your copy do remember to review all your questions and answers. Spare 10-15 in the last to revise the whole paper again.

Hello
Yes, if you’re not satisfied with your marks even after the improvement exam, many education boards allow you to reappear as a private candidate next year to improve your scores. This means you can register independently, study at your own pace, and take the exams without attending regular classes. It’s a good option to improve your results and open up more opportunities for higher studies or careers. Just make sure to check the specific rules and deadlines of your education board so you don’t miss the registration window. Keep your focus, and you will do better next time.
Hello Aspirant,
Yes, in the case that you appeared for the 2025 improvement exam and your roll number is different from what was on the previous year’s marksheet, the board will usually release a new migration certificate. This is because the migration certificate will reflect the most recent exam details, roll number and passing year. You can apply to get it from your board using the process prescribed by them either online or through your school/college.
Hello,
Yes, you can. If you missed the first compartment exam, you can appear in the second compartment exam as per CBSE rules.
Hope it helps !
Hello Prisha
As you have compartment in Mathematics and you wish to change your stream to Humanities you have 2 options from here on:
1. You could try to study and clear your compartment of Mathematics.
2. You can change your stream to Humanities but you will need to repeat from Class 11th so you will need 2 years from now to clear Class 12th.
My personal suggestion will be to choose Option 1. Trust me I have dealt with this feeling myself and wanted to choose Option 2 but I worked hard and cleared my exams. I was scared not only in Mathematics but Physics, Chemistry and even Computer Science.
At last, it's on you what you want to choose.
Thank You!
HELLO,
The GUJCET merit list is calculated by considering 60% of the marks obtained in Class 12 and 40% of the GUJCET score. CBSE students are also eligible to compete with GSEB students, as the merit list is prepared by combining the Class 12 scores with the GUJCET performance.
CBSE Students and GUJCET:
Hope this Helps!
