Hi Kat,

With self study you can crack NEET i am sure about that, just stay in touch with your guardian (Teacher or senior).

fistly. make a schedule for each subject

Divide them as easy subject moderate and hard and then give time accordingly 

Now according to NEET or NTA

Biology is the major portion in NEET examination So, you have to mug up every single line from NCERT (You can follow Aadesh sir videos from our NEETpeJEETseries).

For Chem. numerical, first learn reason behind the formula or learn concept and then Try MCQs (You can follow Arpit sir physical chemistry videos from NEETpeJEETseries)

Thanks for asking

Hope you got your answer
