Any liquid boils when its vapour pressure on its surface is same as of the atmospheric pressure on the liquid surface .But when we add impurities(in this case glucose) it shares the surface with solvent(in his case water). So the pressure on the surface of the solution is also shared therefore, it takes more heat to reach that vapour pressure.

Dont worry... Whatever u hav prepared till date, make yourself perfect in it. As you have prepred for most chapters ...u wont take much time to revise those. If youre left with time after revising prepared chapters, try to open the unprepared ones. But make sure u dont work hard on them...work smart on them. I am sure u have xamidea 100prcent..or any other refresher. Just open it..and try juat to cover the question given there(bcs they are only the most important ones) . Thats it. Best of luck. You can do well.
