Hello aspirant,

One to one classes are more helpful for most students since they get to ask their doubts freely and also because there are no other distractions to the student or teacher. Organic chemistry needs very good concepts and special attention. I feel home tutors will be a better option but if you can communicate well with the teacher in a class full of students, you might join a coaching institute too since both options are same for you. But if you go for the second one, remember not to make much friends or waste much time travelling .

All the best!

Dear Sir / Ma'm, for good concept in physics, you can refer to DC Pandey's Objective Physics Vol 1 and 2. For organic chemistry concepts, you can refer to Chemistry books by Dinesh Publications.Regarding individual coaching or tutor, it emtirely depends on you and what your requirements are.
