      If you have not been taught this before and are self studying then watch this first and then read but if you are being taught in school then read the book and then watch this
      All depends on how much understanding you had at school

      @tpwk9 2 роки тому

      You can do that when you talk about individual polysaccharides ie Starch(it is insoluble so it has no effect on osmotic properties,it is insoluble so it cannot diffuse out of the cell etc) Cellulose it is freely permeable allowing materials to access the cell surface membrane

      @@MaryamKhan-j4m5o Salam, yes a lot of tips and I did really well btw, so please listen to everything, I will go throught it in order, 1. I fixed my sleeping schedule, and started praying five times a day 2. Know your subject, skim through the whole content know the structure of your subject so you know what to expect when revising, 3. I stayed home for a year most of the time so to enjoy revising I had to have a reward system, so in my case I worked min of 6 hours and then at the end of the day I will reward my self with watching few episodes of anime before going to sleep this way I could revise without needing motivation, 4. Make flashcards early, you will be surprised how much you can acctually get done in a day, you can literally finish 3 to 4 topics in a week, so make sure you spend first few months just making flashcards that you are going to use throught the year so you don’t have to go to through the content again 5. You can 100% finish a level biology before January if you rivise 6 days a week, and in January just go over the content for one month, so make sure you finish everything before January, so February/march time you can go past papers for the rest of your gap year, trust me anyone can finish a level bio content in few months so don’t limit your self, you will be thanking your self in January when you have to just go thorught the content one more time before past paper so you will have so much time for exam technique, 7. From February to rest of your gap year all you have to do is past paper so now you can relax you will probably be used to working hard, but this is the time you relax because you already covered the content pretty much all you gotta do is past papers and flashcards now so you will have time to go out with your friends, but before that make sure you commit to your studies till January, 8. One or two months before your exams start to acctually wake up to the time you have your exams, like 1 or two hour before your exam time, and practise how your morning routine and exam day would look like if this was your accrual exam day, this really helps with your nerves, 9. IMPORTANT: make sure you have found an exam centre before the end of November and that your exam board is the same and your exams should be sorted so you don’t have to worry about this, also because if you book late like after January you will have to pay way more for your exams, 10. I had to sit my practicals for biology, so I went to another city it was only for a week, but make sure you book these before December so you don’t have to worry about this later, never put your future self in debt, pay for the exams and practicals and pass your practicals in a week they are very easy unless you are stupidly dumb😂 I’m jk, anyways it’s going to be a long year for you but stay strong and make sure you pray 5 times a day so after Maghrib you can reward yourself, it really helped a lot to organise my day by my prayer times, so stay close to Allah because a lot of times you will think what is the point of this but that’s where you have to work harder and make Dua for laziness, if there anything else you need please don’t hesitate!!
      Lastly I know it’s very long but lastly set weekly goals, like every Sunday that should be your rest day, and so just plan what content you are going to do through each day of the week and check it along the week to track your progress this make you really confident and want to work everyday👍
