Hi reader ,

Look , reading biologicial classification in one go may be a daunting task as you will not be able to retain all the stuffs in one go.

here is what you should do. Instead of reading the chapter at once , divide it in parts.

like first part may be monerans. now read monerans and draw the flow chart as you are reading . For example , you can do like this:

monerans: bacterias = survive in various geographies = 4 shapes = 2 types = archea and eu =  cell wall made of peptidoglycon etc .

now if you do this while reading , all those humongous paragraphs will get simplified in few short and concise lines which will eventually help you retain the points given in ncert. once you are done with monerans try to practice some questions from relevant books . that will take your confidence to a next level. after doing all this move to other kingdom and atlast you will have your  own handmade concise flowcharts

i hope this answer helps

thank you
