# 123IITJEE – JEE Main & JEE Advanced Preparation
## Physics, Mathematics & Chemistry
**123IITJEE** is an online education and JEE preparation portal founded by **Manish Verma, an IIT Madras alumnus**, providing learning resources for **JEE Main, JEE Advanced, IIT-JEE and other competitive examinations**.
The portal brings together **Physics, Mathematics and Chemistry** resources, including concepts, problems and solutions, study material, online classes, recorded lectures, test series and courses for students at different stages of preparation.
The emphasis is on **conceptual understanding, analytical thinking and problem solving** rather than simply memorising formulas and standard methods.
## JEE Preparation Through Understanding
Success in **JEE Main and JEE Advanced** requires more than knowledge of the syllabus. Students need to understand concepts, interpret unfamiliar situations, apply principles, reason logically and solve problems that they may not have encountered before.
123IITJEE is built around this approach.
Students can find resources for **JEE Physics, JEE Mathematics and JEE Chemistry**, together with practice problems, worked solutions, study material and structured online learning.
## Physics, Mathematics & Chemistry for IIT-JEE
### Physics
Physics is a major focus of 123IITJEE, with extensive resources for **JEE Physics**, including concepts, numerical problems, conceptual questions, problem solving and advanced applications.
### Mathematics
Mathematics resources help students develop the conceptual and problem-solving skills required for **JEE Main Mathematics and JEE Advanced Mathematics**, with emphasis on understanding methods and applying them to unfamiliar problems.
### Chemistry
The 123IITJEE learning ecosystem also covers **JEE Chemistry**, with courses and resources for students preparing for JEE Main, JEE Advanced and other competitive examinations.
## Study Material, Courses & Test Series
JEE preparation can involve different forms of learning. 123IITJEE provides access to **JEE study material, online JEE courses, LIVE classes, recorded classes, foundation courses, LIVE 1:1 classes and test series**.
Resources are available for students at different stages, including **Foundation, Class XI, Class XII, XII Pass, JEE Main and JEE Advanced**.
## Problems, Solutions & Articles
Learning Physics, Mathematics and Chemistry becomes much more effective when concepts are applied to good problems.
123IITJEE contains a growing collection of **JEE problems, Physics questions, Mathematics problems, conceptual questions, numerical problems, solutions and educational articles**.
The regularly updated blog forms the continuing stream of new questions, problems, explanations and discussions, while this homepage provides an overview of the wider 123IITJEE learning portal.
