First thing you should keep in mind that “You can crack neet without joining any coaching institute”. I was part of an offline coaching and at the same time i was trying to utilize online content provided in you tube and in some paide platforms. There are multiple YouTube channels which provide lectures and notes for NEET ug preparation. Among those channels my personal favorite is Alakh sir’s channel. Literally they are providing all the lectures, notes, one shot lectures and many more without asking for any amount of money. There all multiple channels of physics wallah like competition wallah, ncert wallah etc in which they cover each and every part of ncert(most important book for neet) , they also cover some extra topics beyond ncert. You can also join pw batches at very low cost in physics wallah app.
Apart ftom lecture and notes they also provide test series, que bank and doubt engine. So overall it’s a complete package. There are several other channels on you tube for your preparation. They are also trying at their level best.
