MBBS is usually considered as the toughest course in biology after 12th as it has a vast syllabus that covers almost every medical subject. Doing an MBBS involves practising clinical rotations and undertaking responsibility for patient care.

The authorities have provided the weigtage for COMEDK UGET syllabus for classes 11th and 12th. The topics from class 11th hold 33% while class 12th topics have 67% weightage in the entire question paper, across the 3 subjects.

The "best" course for PCB or PCMB students after 12th depends on their personal interests and career aspirations. Here are some of the best course options for those interested in the healthcare fields after 12th (without becoming a doctor):

• BSc in Biotechnology
• BSc in Microbiology
• BSc in Nursing
• BSc in Public Health
• BSc in Occupational Therapy
• BSc in Health and Nutrition

For someone who is not interested in working in the medical field after class 12th, the popular courses are:

• BSc in Environmental Science
• BSc in Marine Biology
• BSc in Agricultural Sciences
• BSc in Food Technology

The 12^th standard PCM marks will be considered to break the tie in the BITSAT score. If the tie remains after checking the entrance exam subject-wise score, then the 12^th standard qualifying exam marks will be used to break the tie.

Yes, previous year question papers are very helpful. They give you a clear idea about the type of questions asked in the exam. You can also understand the marking scheme and important topics.

Two vectors which are parallel to each other, irrespective of direction, are called parallel vectors.

Enzymes found in human bodies are 

• Lipases: They remove the fats in the gut.

• Amylase: It is present in the saliva. The role of amylase is to break down carbohydrates.

• Maltase: These enzymes are found in the small intestine. It breaks down the sugar maltose into glucose. 

• Trypsin: These enzymes are present in the small intestine. The function of trypsin is to break proteins into amino acids.

• Lactase: The function of lactase is to break down lactose into simpler sugars (glucose and galactose). Lactose is the sugar that is found in dairy products.

We can define enzymes as biocatalysts. It is important in biological processes like digestion, metabolism, and the synthesis of cellular components. If enzymes stop their functions, then the body can not generate enough proteins, which is important for survival. The examples of enzymes are lactase and amylase.
