## Conclusion

Physics is one subject that challenges every student. There are a lot of complex theories and derivations involved in Physics. The students must figure out their weak and strong areas and work accordingly.

Candidates are suggested to appear for the mock tests frequently to analyze their preparation. Along with the studies, do not neglect your health.

*Good luck with all your future endeavors! *
