TIPS :

Be knowledgeable in all IC pin details .this will surely help u to get more marks in first unit study all base planar process. So that u can attend both part A and part B question.

In case of 4th unit , study both PLL and VCO question so that u can attend one part B question (99%). In 5^th unit ,study function generator and switching regulator (especially )..it may come surely ....
