See this is a question on which you get n number of different answers since one cannot predict such things. That basically depends on how sharp your memory power and understanding concepts speed is. It can take x days for someone then at the same time it  can take 2x or maybe 3x days for the other one as well. Its about quality and not quantity. But I understand your query, so i will like to motivate you and help you out for sure. See try to go step by step and deep by deep. Select a particular topic like for example if you select the topic modern physics then it has 4 chapters inside this heading, then firstly do atoms,molecules and nuclei, then go for electrons and photons, then semiconductors and finally the communication  system. If you study with concentration and dedication, then you can finish this maybe within 2 or 3 days maximum. And obviously the link will be maintained, Then you can go for other topic like maybe Sound and Waves, then it will have 5 chapters within again repeat the same process of going step by step and more and more deep. Your concepts will keep getting cleared.

Feel free to ask any further queries below..

Thank you.

Hey there

It depends on a lots of factors like

1. If you are starting from beginning then it may take you upto 5-6 months or more to complete every chapter clearly.

2. Under good guidance of teacher you may cover it within 4-5 months or bit more depends upon you and your teachers hard word on the subject.

The factor which matters most is you as physics is challenging but if you devote time everyday you will be able to complete it shortly.

Good Luck
