I use to teach by step by step method i.e by making every single word and sentence clear to my students and help them have more ideas in the field and make a clear description of any diagram used for purpose of teaching but I have some rules and regulations but it's not new to because you hear them in your learning journey by many teachers and I will not listed them because when ever you hear or read teachers rules and regulations,the rules were know by any students,so l will not waste my time explaining rules that you already know them.Lastly you have to attend every single class if you want better ideas and have a wider knowledge in my field and do not consider physical appearance of person because knowledge is not about do we you look,it's sharpness of brain and always do not consider age of person in learning career because God make everyone with special capability and He who give them the capability do no see there age or there physical appearance so do say or put in to your mind that this person can't teach me because is too small or he do not look like that experience that he claimed to be if you say so then if care do not taken you will be the unknowingly person in the whole if you are interested to master biology and pass you examination and test follow my instructions and criteria of teaching and be present all the time thank you.
