Hello. Yes, you can do M.Sc. in Chemistry or Botany as a private (non-regular) student — but only in a few universities in India, as most UGC-recognized universities do not offer private mode for postgraduate science courses due to their practical/lab requirements.

M.Sc. Private/Distance Mode is Rarely Available for:

Botany

Chemistry

Because t hese subjects involve lab work, practicals, and experiments, which cannot be completed through distance/private mode easily.

Universities That Might Offer M.Sc. (Private or Distance Mode):

The SN1 mechanism (Substitution Nucleophilic Unimolecular) is a two-step reaction where the leaving group first departs, forming a carbocation intermediate.
Next, a nucleophile attacks this carbocation to form the final product.
It usually occurs in tertiary alkyl halides due to the stability of the carbocation.
The reaction rate depends only on the concentration of the substrate, not the nucleophile.

Hello

Hii,

If you passed Class 12th in the first attempt, and later appeared for improvement/betterment but failed in Chemistry, your original mark sheet from the first attempt remains valid and accepted everywhere.

The betterment marks are optional they’re only used if the improved marks are better than the original. But if you performed worse like failing in a subject, it doesn’t replace your first result. So don’t worry, your original 12th pass certificate is completely valid for higher education, jobs, or competitive exams.

Hope that clears your confusion!

For NEET exam, you have to study all chapters from Physics, Chemistry and Biology. If you are a Hindi medium student, still NCERT books are the best to prepare. You must know how many total chapters are there so you can make a proper study plan. In Chemistry, there are around 30 chapters, in Biology also more than 30 chapters, and in Physics around 30 chapters. You have to prepare all chapters equally because NEET asks questions from all subjects.

• NEET includes Physics, Chemistry and Biology
• Each subject has around 30 or more chapters
• NCERT books are best for Hindi and English medium both
• Every chapter is important, do not skip any
• Make a daily study plan to complete syllabus on time

Hello Aspirant,

Yes, you may study either bioscience or mathematics at graduation level based on the eligibility requirements of the university or college that you are applying to. Since you have studied PCMB (Physics, Chemistry, Mathematics, Biology) and also Physical Education, you are eligible to pursue both streams of study. However, as Chemistry is marked as an extra subject, some institutions may not consider it one of the three core subjects required to gain entry into a B.Sc. (Bio-Science) program in certain specializations.

• B.Sc. in Bioscience: Most Universities expect Biology and Chemistry as core subjects. If Chemistry is an addition subject, then check to see if the University accepts it for eligibility status.
• For B.Sc. in Mathematics or related fields such as, Physics, Statistics, or Computer Science: These subjects typically require Mathematics only, and Chemistry is likely an additional subject - so, you should be eligible for these.

Hello Aspirant,

Yes, if you have passed in 5 subjects including English, Biology and Phyiscs BSc Nursing can be pursued. However, the chemistry is also a core subject for the nursing eligibility and to met the eligibility in full, you must be able to get a pass in the RT (Re -test) in Chemistry to meet the eligibility criteria. Once you get a pass in Chemistry, you should be eligible for admission. The requirements may vary slightly from one college or University to the next be sure to check the college or university you are applying to your specific requirements.
