In this post b.sc 3rd year botany syllabus is given for 2023-2024. 

The syllabus covers all those topics which are in the syllabus of any university. 

This is a common syllabus, which will act as a guide. 

This will guide those students who have just entered the third year and their university has not provided the updated syllabus. 

By covering the topics given in the BSc 3rd year botany syllabus, you can make notes for yourself in advance and make good use of your time. 

You can also download this syllabus in PDF. 

Students who have not yet received the syllabus and want to make good use of their time can continue their studies using this syllabus as their basis. 

If your university has released the BSC final year syllabus and there is a difference in this syllabus from its topic, then of course you should follow the syllabus of your university. 

The syllabi of all universities may be different, but some topics are common in all of them. 

Therefore, there should be no problem in following this syllabus. 

For better information about all these topics of the BSc Botany honors syllabus, you can also get help from an advanced book on this subject. 

This will increase your confidence level and also your knowledge level. 

The syllabus given in this post covers the topics of Paper 1, Paper 2, and Paper 3 of Botany Third Year. 

These have to be studied in B.Sc Botany subject.
