Please provide specific information on the enlarger and/or multigrade head you're using. Post a photo of the actual setup if you can.
For the popular Ilford 500 system, a light meter is/was available, but it was an optional accessory. I've come across it once or twice, but most setups I've seen, didn't have it.

Here's an example of an Ilford 500 setup without the actual exposure unit/light source. I've circled the metering probe. Also pictured is an accessory foot pedal. Like the probe, it's often not included in the setup.
Note furthermore that Ilford to the best of my knowledge never made any enlargers. But their variable contrast exposure systems are quite common on the second hand market and could be fitted onto several enlarger frames. There are several versions of these units, hence my question to you to please specify what you have there.
Making test strips is a dependable and entirely acceptable way to work towards a first full print. I've done lots of work with probes/meters etc., but ultimately, I've always gone back to test strips/prints as they are an absolutely accurate and intuitive representation of what the actual print will look like. It also requires very little theoretical knowledge to use this approach. I strongly recommend listening carefully to your teacher and following his instructions. Once you understand the basic process, it's much easier to start to explore alternative ways of working.
