Hey!

Though you have not mentioned which syllabus you are referring to, however whichever syllabus it is, to complete the readings of the syllabus it will take as much time as you would devote into it and your capacity to go through with it. Reading the concepts won't take much time but understanding the concepts and practicing will definitely take much more time than just reading the concepts. You should make a time table as per your routine, keeping in mind the time left to complete the concepts and follow it accordingly. If you follow it religiously then you will be able to complete your syllabus just in time.
