VITEEE checks and select students on the basis of concept, speed, accuracy, time management and decision making power. VITEEE paper has no negative marking thus try to attempt as many as question but keeping the factor of time management in mind. Sample papers are the best source to judge the level of preparation you have done. So, try to take help from previous year papers and sample papers for better preparations. First and foremost while preparing for VITEEE, ensure that you know your CBSE/State Board syllabus thoroughly. Nothing out of the syllabus is going to come for the exam.

The CBSE/State Board textbooks are very important in the following units:

Inorganic Chemistry 

The type of questions asked in competitive exams under this part of Chemistry will directly be based off the reactions given in the standard text book. Chapters like s-block, p-block and d-block elements come under this category. Do the exercise questions given at the end of the chapter first. Some of the questions are frequently asked in competitive exams like JEE Mains, BITSAT as well

Coordinate Geometry

The topic is a vast topic and one can go on and on while trying to prepare for it. But with respect to competitive exams, stick to NCERT syllabus for it. It is also useful to practice drawing graphs for various equations as that technique might come in useful in visualizing certain problems that might be too lengthy for solving mathematically.

Semiconductor Devices and their applications

The CBSE book for Physics is the primer for this topic. The book pretty much covers everything required in this topic. Some of it might be useful in college courses like Metallurgy. Other reference books that can be termed as best books for VITEEE preparation by many students are:

Physics Arihant Series, DC Pandey Books on Mechanics- Part 1, Mechanics-Part 2, Waves and Thermodynamics, Electricity and Magnetism and Optics and Modern Physics. Concepts of Physics (both volumes) by HC Verma,MCQ Question Bank by D Mukherjee, Chemistry Inorganic Chemistry NCERT Text Book, Organic Chemistry Khan Academy Videos. Mathematics Arihant Series-Dr. SK Goyal, Arihant Past Year AIEEE papers, VITEEE Solved Papers and Mock Tests from Arihant. RD Sharma, Objective Mathematics Part 1 and Part 2 (NCERT difficulty), Biology NCERT Text Book, AC Dutta for Botany, Oxford Publication. Pradeep's Biology Guide.
