While it is a harsh reality that we have to give up a plethora of our time to succeed in our subjects, it is a fact of life. However, this time need not be an excessive amount if you efficiently and effectively apply yourself. One such way to achieve this would be to purchase Kamal's notes. By being highly refined, thoroughly covering EVERY syllabus dot point, and elucidating difficult concepts, his notes make the best use of your study time. Not only this, but they incorporate pertinent diagrams AND HSC questions. This is invaluable to your HSC as practice is what defines your success - especially in Science subjects.
To look past his notes would be to deny yourself a distinct advantage over your cohort.
Kamal's exceptional ATAR and results are reflective of his skills and abilities, which are undeniably apparent in his notes.
It is irrefutable that his notes are critical to your HSC success. It was of the highest of pleasures reading through them.
Have a nice day guys and best of luck with your studies!
