Dear aspirant,

Although the question papers of the both the exam is based on the syllabus of 11th and 12th. There is much difference between level of the exams and type of questions which are asked in the exam.

For neet- You can solve a part of  chemistry questions without even writing a single thing on a rough paper . If you have a good practice from previous years you can easily score marks here. It does not require any out of the box thinking.

For jee- You will also get questions here for which you do not need to do any kind of rough work but the difference is they are only a handful. The sums here requires some critical thinking. You really need to think on some sums to get the answer.
