* this video is made by my friend Moiz Ehtesham. he is one of the smartest person i studied with during my step 1 journey. He will be teaching on this channel along with me. his method of teaching will be a great help for everyone.

*If you are first or second year medical student or if you have more than one year to prepare for usmle step 1 or any other exam then i strongly recommend you to watch dr. najeeb lectures to make your concepts very clear. If you don't have enough time to prepare for usmle step 1 then i would not recommend you to go through every video of dr. najeeb . just watch neurology and immunology.
